Asked this question on another site's forum, but I guess no one had the time to read through my long-winded inquiry. No one responded. :-( So, I've edited it down a bit for this forum and am giving it another shot.
I really like the Tensei Blue shafts I play in both my TS2 Driver and 818H2 21* hybrid. I was fit for both clubs, as well as my 917F2 15* fairway, which has a Diamana Blueboard in it. All are in a stiff flex.
To make a major edit here, I will leave out how I came into possession of a new TSi2 16.5 3/4 fairway metal, but I did, and at a great price. Unfortunately, it has a shaft in it that does not fit me that well, a KuroKage 55 R flex. So, in my head, that won't work. Consequently, I'll need to replace the shaft with something else. Since I was fit for Tensei shafts in my driver and hybrid, I would think a Tensei in the new fairway won't be detrimental in any way. So, I will start looking around for one to plug in. In the meantime, I could swap out the Diamana that's in my 917F2 3W for the time being.
I'm a tinkerer. I like to try different shafts anyway, so "getting fit" is not something I do when I'm "tinkering" if you know what I mean. Fitting by tinkering is the whole fun of it.
Though I plan to put a Tensei in it, I am thinking about trying a PX Evenflow Blue driver shaft I have sitting around doing nothing. It was trimmed about 3/4" shorter than the Tensei I usually play in my driver....as an experiment. (I got the Evenflow for basically nothing so figured, what the heck! Chop it down and see what happens.) Though I don't mind the way the Evenflow feels in my driver, I think it subconsciously bothers me it's a 3/4 inch short, and as a result, on center contact strikes, I'm giving up distance. Whether that's actually true or not doesn't matter to my over-analytic mind. So, it sits in my garage doing nothing.
That said, I was thinking of cutting it down further to try in my new TSi2 3W head, again, as another experiment. Will it play stiffer if I trim it only from the butt end (so I don't have to replace the Titleist adapter)? I already cut the tip a little to put the adapter on in the first place, since the shaft was not new when I got it and the tip was a bit rough from the initial pull procedure. I know PX Evenflow shafts are the same for driver or fairway, with only different trimming instruction, so I think this is feasible. It's a 5.5 flex (R+), but I assume cutting it will stiffen it, which is okay by me, as long as it doesn't make it too stiff. How much will it affect swingweight by taking 2" (approx) off the butt end? A little heavier swingweight is fine with me. I like to feel the head in my swing.
Opinions appreciated. What say you? Anyone?
