Ironically, one might almost make the case that #6 Lehigh is a better risk/reward par 5 than its mate #11. It certainly seems it might have a wider variety of choices and considerations to it.
Clearly, #6 has nothing to it as fetching and dramatic looking as the top of the hill approach to #11 but look at what the golfer can be faced with throughout #6 compared to #11 and the variety and number of nuancy risks on #6 compared to the more straightforward and obvious choices and risks on #11.
First of all I've played #6 from the much shorter and left side tees the last few times there (why are they there anyway and are they original? Why doesn't the club just go with the tees that are nearer #5 green and probably the originals?) I do remember the times I've played #6 in tournaments from the back tees that the drive is quite complicated with the crossing bunkers coming into play more from the back or seemingly so. They really appear to be in play but really aren't and consequently create some interesting deception. I understand that Ron Forse added a few of those cross bunkers that eat out to the left on the drive and more in-line with the fairway and I feel they are very good (at least for deception). So even from the left side tees that are more inline with the hole the drive on #6 is far more complex and interesting than #11. There are more interesting choices and angles and club selection possibilities on this drive! Most players tend to go too far left and too long on this shot to a basically blind fairway area (hidden just enough by the cross bunkers). So the ideal shot would seem to be to deal with the tree-lined right side far more than one would think or expect here to get into the middle of the fairway and have a good shot at the green on this relatively short par 5 (go/no go, risk/reward par 5).
If you err long and left on the drive (even with a solid but less well thoughtout drive) you have a complicated and multi choice recovery style second shot that definitely needs to deal either short or long with the necked in flanking bunkers about 100+ out which are also excellent architecture creating many strategic possibilities. One can take them out of the equation by laying up short of them but then you have a longer iron into a very complicated green due to the excellent squeezing front bunkers (both sides) and the narrow front tongue of the green (also excellent) and some fairly severe slope right to left on the green and its surround.
Say you want to go for this green in two. How exactly are you going to do it and how and where do you want to try to miss it if your shot isn't spot on. There is much to think about here compared to basically crossing the river on #11. What if you come up a little short and right on #6? What if the pin is in the front tongue? What in the world are you going to do then and think of the temptations to try to be Phil Mickelson and the potential to put yourself behind the 8 ball if your not. How about if you're in the right bunker--that's just as bad!
But say you don't go for the green in two and say you even just try to play the entire hole conservatively (not really a hard thing to do strategically) until you're faced with the third shot. This is why I really like this hole because it has two completely separate dimensions depending on where the pin happens to be! If the pin is in the back the hole is one thing that's quite straightforward and not particularly demanding. But if the pin is in the front or near it then what are you going to try to do exactly? You can try to hit a little wedge, SW or probably an L wedge near the extremely narrow green space pin in front (this area actually caps off and makes the entire hole!!). But this one has to be good and a slight miscue will very likely result in a bogie when you were so near this hole with the opportunity for a birdie or a conservative par. Miscuing here this way can send most golfers into a very bad frame of mind (not a good thing with what comes after #6!). Or being so near this green with its front pin you can just elect to play well beyond the pin and putt back likely giving up your birdie to settle for a safe par. This aspect and this part of the hole is almost the ulitmate in subtle and sublime temptation!! This is the shot and choice that really tests a golfer's concentration, execution and management skills. Nowhere near as dramatic looking as the approach to #11 but probably better all things considered. I would definitely take my chances in succeeding in getting up and down having missed #11 than I would having missed #6 on the right to a front pin.
I don't think I would call #6 one of the best risk/reward par 5s in the country either but it's a very good one if you try to get too aggressive with either the tee shot or with the go approach or very much even the third shot approach if the pin position is in the front super complex spot.
Both interesting and good holes as is the rest of Lehigh! But as I said much earlier these two par 5s had better be interesting and complex because it's rare and a bit hard to defend a par 70 course architecturally that has ONLY two par 5s that are very reachable!
Mostly the better known and more respected classic par 70s like Merion and Pine Valley have opted for the much longer and almost unreachables for their two par 5s!
Thinking about the classic par 70s with two par 5s, I might have to say that Huntingdon Valley's #7 is as good or better a go/no go, risk/reward par 5 than these ones, but maybe not. Going for #7 HVGC is definitely as demanding and exhilirating and if you don't, the layup possibilities are far more varied!
