As per a suggestion from one of our members here, I picked up an Excaliber Ibex, and have never looked back. Very good bow for the money. I'm looking to upgrade the scope. It's functional, but I want a better piece of glass on it, and I'm sure the bow will shoot tighter groups.
If you want tighter groups you gonna need spine indexed arrows, not necessarily another scope. Of course it couldn't hurt tho..I use spine indexed Spynal Tapp arrows from Southshore archery supply in my Tenpoint FX4. Tremendous arrows......
