-Zick Kit "No Kick Kit"
-Halo B with Rip drive and Victory Board, Hybrid suicide shell
-88 CI/4500 PSI Carbon Fiber Pure Energy tank
I would have to recommend the Zick kit which eliminates alot of kick. I had never shot my marker before putting this in but had heard rumors that Etek's can pack some punch without it. Other than the Zick kit one might consider a star frame, basically with a star frame, the new QEV that comes with the star frame, and a Zick kit you have an Ego '08 for a couple hundred less.
OH ! and I almost forgot the Cure Bolt, Im getting one this weekend, supposedly the best bolt thats out there, eliminating chopping, breaking, etc.
-Easy to Clean
-Accuracy, Consistency, Speed
-Screws come loose easy
-None I can really thing of beyond that
All in all this is a great marker for the money. It doesnt get any better when your holding a marker that feels like it should cost double what you paid for it. Planet Eclipse really thought this one through and it shows with performance and looks. A great all around marker that is easily one of the best out right now.
If you have the money, and are looking for a great tournament marker buy this thing.
