Like Bue says, it might be better shorter. After #1 at 60" blew up, I built #2 at 58" , and it worked ok but didn't make the chrono smoke or anything. So for #3 I still used the superlam to get the tip wedge but added a stabilcore under glass both sides. It is quite torsionaly stiff so might be able to do without the tip wedge.
Not sure about more taper, but that might help too.
If I can pull it , it will prob end up my fishin bow. Prob end up 50+ .
A bit of camo paint and good to go...
