I had an Ibex and it is a greaat bow. Shoots nearly everything you put in it very accurately (do not recommend shooting at the same spot twice out to at least 40 yards - don't ask how I know).
The factory arows shoot well, but after trying several different makes, I went to Deer Crossing for quality and price. I shoot Swhacker 100 grain heads and had no problem at all getting field points and broadheads to group together.
If you decide to try Deer Crossing arrows, code Joe53 is good for 10% off at check out.
Have fun with the young ones!
