My son had the CF3 last year and it just didn't seem like it had the same pop as the Catalyst as far as "composite" bats go. The Voodoo was also used by several players on teamwilson and it was a solid bat.
Have not seen any end cap issues in over a year. We have several boys using either the CF3 or Voodoo. Last night my son just flipped his wrist and send a line drive 300' into the right field gap with the -3 -- and he's not a big kid.
