W2 trim code in the 08, 09 golfworks catalog-
Stops there....and same 1.0" for 6, 7, 8, 9woods
To muddy the waters the 08, 09 hireko catalog is a G 1 trim code, same trim as GW, but with the following notes, for an m1 bore = add 1.5", m2 bore = add 1.0", and for a blind bore = add 0.5"....Basically measure the bbgm and add that amount to the trimming. Some of the old grafalloy wood shafts had the same trim instructions as they were originally intended for thrubores.
From memory, the chatter about this shaft was that the stiff was stout, but the regular played true or even a tad soft. There is a thin steel layer so you need to be careful with the tip prep, ie do not a abrade like a steel iron shaft. It came with a green label towards the tip telling you to be careful.
