Yep I think he was trying to say under spined! Ausi has or is inprogress of building me some archery ammo and the FOC is up around 19-20%! He knows what he's doing so I'm trusting him...if they wobble like a fat woman at a buffet I'll cry and just blame it on my poor shooting.

I can already prepare to adjust my sights since I'm shooting stock 340's and some 400 spine with 100 gr field points,but I'm still learning and hoping to select BH's for hunting soon.
