masgolf:i will try to leave myself somewhere between 90-100 yards out in order to not have to mess with half shots etc.
Precisely why the extra wedge coverage will lower your scores. Hitting mostly full 75 yard and 50-60 yard wedge shots will lead to many more birdie opportunities than hitting either full or partial 90 yard ones. Your shots should, and will, be closer. In addition, executing a 10 yard pitch is much easier with a 15 yard club rather than a 30 yard one. For further evidence, check the bags of the top players on the home page.
Just give it a try. Heck, its only another 200 credits at this point if you buy a new one. :) Unless you already have Pro level wedges bagged that you're not using, I might look to the Ping 64* that goes 60 yards full. The starter 60W will give similar performance without the precision and spin potential.
Good luck either way.
