I don't see a lot of mold minimalists in my area, and the top pros (Ricky, Eagle, Paul, etc) are still bagging 12+ molds.
This is interesting. I was actually watching his (McBeth's) 'In the Bag' from last year, and by my way of thinking he seemed to play primarily 3 main molds, which seem to be his 'meat and potatoes'. Aviar, Roc and Destroyer. The video I saw the largest number of discs per mold in his bag were Rocs and Destroyers (at 8 & 6, if memory serves).
I'm not saying this to 'prove my point', I'm saying that typically an experienced golfer's game is based on a limited number of molds, especially when considering the general percentage of strokes made with same during a 'typical' round. I also say this as a tip to less experienced people wishing to speed up their learning curve and eliminate variables...
I see your point, though, I guess it's how technical one wishes to be, for example, while the Roc and Roc3 are different molds, I would consider them 'the same' for the purpose of making my general point...Your point seems to be that an expert knows how to take advantage of all of these smaller differences and in fact, requires them to compete at the higher levels...fair enough.
In my day, people could win on the strength of equipment alone. If you were the guy connected enough to have a couple of Aeros and the other guys had Midnight Flyers, you were feeling pretty confident. I still remember the day I got my first Aero (patent pending btw)...
