I agree with Tom Doak here. I think its fine if you have a fairway that lets you hit straight for say 240-250 yards but if you want to go longer you either have to curve the ball or hit over the corner. And its fine for a chute of trees (or a single strategically located tree) to make it difficult or impossible to take that "over" option and only leave you with the option to curve the ball. Guys who can work the ball can hit it as far as they want. Guys who can't have to lay up to the corner off the tee and play a longer approach.
Phil,
I don't think I agree with your premise here. I don't see a problem with trees off the tree making it difficult for you to play a draw due to the way they line up. They shouldn't line up so that you can't play a straight shot, but you shouldn't expect to be able to play the draw off every tee. The architect is requiring you to produce a straight shot (or a fade) and if you can't play that shot with the club you'd prefer to use off that tee, you'll have to choose a different club which you can hit a straight ball with.
One thing that annoys me in this regard is when architects fail to take the prevailing wind into account. My home course built a new tee for the 9th hole some years ago, which is set at an angle quite a bit right of the straight down the fairway path. The fairway runs sort of SSE, into the prevailing south wind, which acts as a nasty quartering wind into you from the right from that tee. This makes it tough because you want to aim right to allow for the wind, and the worst trouble is on the left -- moguls, blocking trees, etc. There are bunkers right but the furthest is only about 240 off the tee so very easy to carry these days even into the wind (they used to be a real pain 10 years ago before the modern ball and big headed driver gave me 30-40 yards more carry into the wind)
The problem is that there are two large trees that overhang the ideal line I'd like to take with a straight ball. Since the tee shot is very steeply uphill the first 150 yards, its not possible to hit over those trees, and the stronger the wind blows the more the branches overhang that line! So I'll yank every other drive left in an unconscious avoidance move plus manage to hit the overhanging branches about once a season. Clearly when that tee was added they didn't think about the consequences of those two trees, and haven't seen fit to remove them (the pro plays a nice holding fade so he doesn't see the problem
)
I'll grant that before the big headed driver made hitting a controlled holding power fade into a quartering wind a task for only the most accomplished players that this wasn't really a big deal. When the wind was blowing 20 mph, pretty much no one could carry the far bunker up that hill, so you had to hit a fade anyway. But the equipment has evolved in the meantime and now this hole has become more difficult in many ways as a result despite added distance taking the bunkers out of play!
