Re: ShopTalk: Clarification needed

Dave, isn't the half cpm slope reduction a reflection of the 3/8-inch 
length increments you get with standard head weights and MOI matching 
instead of 1/2-inch length increments with swingweight matching?  I believe 
Tom Wishon's system adds weight to the shorter (than the 'favorite') clubs 
to preserve the 1/2-inch increments, in which case wouldn't the cpm slope 
not be changed?

Personally, I prefer the standard head weights and shorter length 
increments you get with MOI matching - I like the shorter long irons and woods.

The procedures are compatible. The thing that makes it compatible is that 
tip-trim is an "independent control". Depending on where you trim the 
shaft (not length, but WHERE on the shaft you get the length), you can 
affect the frequency without touching the swingweight or MOI.

So you can match both frequency and MOI, just as you could match both 
frequency and swingweight.

That said, if you tip-trim as if you were making a conventional 
(swingweight-matched) set, your MOI-matched set would still have a 
straight-line frequency match. But the slope would be reduced by about a 
half cpm per club. (e.g.- instead of 4.3cpm/club, it would be 
3.8cpm/club). That's probably not enough to worry about.
