We have never carried the Veylix shafts, so a shaft trim guide from us in 2017 product would not have any guidance, unless I am misunderstanding Rlafoone and the shafts he is referring to. As far as the trim, if you want a softer feel or a higher trajectory, trim less. If you want a firmer feel and a mid to lower trajectory influence, trim more. Also, the head weight of the #3 wood is a factor. A lot of #3 woods today have light head weights. 208-212g is probably the average range, but we see many at 205g. This is due to the longer lengths of todays fairway woods. The lighter the weight, the less you want to trim. Be sure you know what the parallel tip length is on the shaft and the bore depth on the head. Sometimes trimming 1.5″ on a 3″ parallel tip length can cut it close if the bore depth is 1.5 inches.
