KBacon is right, the Gold tips are very good arrows and the prices arent bad. I am shooting the gold tip hunters 5575 out of my PSE with about the same setup as you. At the shop were i buy them they are 65.00 a dozen, but i have seen them through mail order places for less. I think they are like 49.95 plus s&h and cutting to length from
www.keystonecountrystore.com. I have paided more for XX75's before. Carbons arent indestructible though, they wont bend but they will shatter if you hit something really hard. I have never had one bust going through a shoulder blade, but they dont do well hitting trees or the rebar in the legs of 3-D targets. They are definetly worth a try.
