-Fast rate of fire
-Less expensive than E-Grip
-Allows full usage of the Cyclone Feed
This kit, to me, is the best upgrade for any Ttippmann. It shoots just as fast as any E-Grip and is much less cost-wise. The only thing I found a little different is that the A-5 R/T seems to be slightly harder to tune and the 98 R/T seems to have more control. I feel it easier to shoot exact bursts and a long automatic stream with the 98 than the A5. Maybe I didn't tune my correctly yet, but if thats the case, its taking a little longer than the 98.
If increased rate of fire is needed, than definitely consider this. It can equal or even outshoot the E-Grips ROF if tuned right. Also, you dont have to worry about feed problems with the A-5. Well worth the extra money, and the R/T is very reliable, although for me, the control is a little inconsistant.
