Actually, as a higher-handicapper, I think I actually have an advantage there. I don't hit any club in my bag with razor-like precision, so I don't know that the transition will be a huge impact. In a blind test would I hit a Adams 6-iron significantly different than a Callaway? Probably not.
My bigger concern is actually my fitting. I want to be sure we have adequate time to find the right clubs and shafts. It's hard for me to believe it's going to get done in the typical hour session. Since I plan on driving down to the Callaway Performance Center in Memphis (3.5 hours away) to get fitted, I'm going to see if perhaps I can schedule two fitting blocks, just to be sure I have enough time. I'd hate to spend all my time on the irons and then have them go, "Sorry, we're out of time, but here's a good guess on what will work for a fairway wood."
