if you cut the club at the butt end you will make it stiffer in number BUT you will hardly feel the difference
probably increase stiffness by 2-3cpm max. negligible imho. now trimming a reg shaft is a diff story, youd feel
that for sure. dont expect to get a full flex up with tip trimming, remember your going thru sub flexes and are lucky to get half
a flex up. danger of tipping too much is you will affect the original characteristics of the shaft. be careful but have fun.
weve all been there.
