RE: vipertec or razortec
Pa is correct. If you are going to only hunt with the bow and not really take spots or 3D too seriously, the Vipertec is a great bow. I own one right now and if I had the budget for a 3D bow as well, I'd keep my Vipertec just for hunting.
If you want a good all arounder from Hoyt, the Xtec seems to be mighty popular.
