High handicap does not equal short hitter. I'm a 17 (sadly) but hit it as long/longer than all but a few near scratch golfers at my club.
But do you really out drive those scratch guys when you're hitting 3 off the tee?
Im kinda just kidding -- I'm oftentimes the same way. I'm long (tall and lanky) and can boom the driver, but I can hit OB left and right indiscriminately lose plenty of strokes by hitting 3 off the tee. Enough to keep me in the same 15-17 range as you.
And I know all about the slope (I'm a statistician) but that doesn't mean courses SHOULD be rated for a bogey golfer from tees no bogey golfer should be playing.
Jason - hitting 3 off the tee (along with needing improvement in my short game) is pretty much the reason I am a 17! Mind you, I prefer not to play the back tees at most courses, and I think it's a bit absurd for me to try anything 7000+ given my abilities. At my club, the back and middle tees are actually not much different in length, but I still prefer the middle tees, because the main difference is in 2 long par 3s that go from around 190-210 to 210-225. Those can be pretty daunting shots if the wind is in your face. Also, 18 goes from a reasonably difficult 350 yard hole with trouble right and left and a steeply uphill 2nd shot to a well bunkered green, to a 420 yard hole with all of that, plus a 200 yard carry over a creek for your drive. Again, a very doable shot for me, though its fairly challenging mentally knowing how much trouble I can get into.
I just reject the argument that if a course is too difficult, you must be playing the wrong tees. While length is a big factor for sure, the width of fairways, thickness of rough, amount of trouble off the fairway and around greens and degree of difficulty of putting surfaces all play an important role. In match play, I will have a better chance of winning on a long but wide open course than a short and tight one. No two golfers games are alike - high or low handicap.
Along these lines, it will be interesting to see who comes out on top at Merion this year - it is obviously short and will play tight, but I bet the greens will be borderline absurd.
