Yea, im planning to buy tippmann x7, its good when you can choose between auto and manual shooting
Note with the standard X7 you don't get this - you get the selector switch, but thats just for safe & mechanical semi.
With upgrade trigger grips you get additional modes on the selector.
With the X7 Phenom you get safe, mechanical semi, and FA which selects the electronic mode, which can be programmed from the available modes.
Just for reference - you cannot use full auto on UK sites, certainly for safety & insurance purposes.
For the cyclone on the Tippmann 98 I would say it is not realy a worthwhile upgrade these days, the 98 is fine as is. Get a 95 or X7 if you want a cyclone.
