If your getting no chopping issues with the cure 2 then there is no need to change. I had a cure 2 in my gun last year and had no problems. Bought a cure 3 just because I like new toys, again had no problems. Performance difference? None at all, had chops with neither
I believe there is no Zick kit for the 06 ego, just the 07 onwards.
What you can get though is a Ti rammer from Warped Sportz. This reduces the moving weight inside the gun, and reduces kick!
thanks mate just that i have been looking on the net and been getting dirrerent answers for the zick kit but for the bolt i like new toys as well lol thanks mate
