I've used Angels to Ions to Tippmans but personaly I like the Fly a ton more.
It's mostly that I'm impartial to WDP.
I use my Tuxie Custom
14in Stiffi, Rocking Trigger, Custom Board, Break beam eyes, CCM low-rise feedneck, and a Smart Parts Max-Flow
Maybe a new barrel
Fast, Fast, Fast
Tears through paint
I used my friends Fly and I loved it. Through three cases of paint it only chopped once. I scared the **** out of my team when I showed up for practice with it. There was one time when one of the players on my team during practice that continuously shot me in the back of head, on purpose I hope or I would feel bad about what I did next, so I emptied my entire Halo on him in like 4 seconds. Once again really f***ing fast. If there is any way for you to get ahold of this thing DON'T LET GO!!!
If you can,get. If you can't find somebody that does and make sure they leave it to you in their will.
