Project x 5.5 v px lz 5.5

I have these in my AP3 s I find them a great shaft with quite a high launch compared to the Rifle shaft.
to be honest the difference between 5.5 and 6.0 was not noticeable to me.
If you have the speed 6.0 had a slightly better dispersion but minuscule.
I don’t think they are as long as the rifle but that might be me and the lofts on the AP3s .
I have the 115g ones but a fitter will sort your weight out as am not sure what lighter shafts are, 95g I think .
I would recommend them but you need to try for yourself.
