I wouldn't worry about it. The sims around here have really nice mats for hitting off of. They have longer grass for rough, even longer for Oakmont style rough and some soft, wispy stuff to resemble sand, which actually works pretty well.
If you're hitting forged clubs, you could tweak them in terms of loft and lie, but I honestly doubt it would happen unless you're a real pelter. If you're taking divots in the sim, maybe tone it down a bit.
I played sims all last winter and had no problems with my 33's.
