Xfps Combo (NOT for joysticks)

Trying to get used to keyboard and mouse on my pc with fps. Looked a little into it and apparently, the new xfps sniper w/ a smartjoy frag combo makes it work real well on a 360. Wanted to know if anyone has tried this configuration yet on here? I don’t care about the ps2 port since I already have a sanwa stick for my 360 but I wouldn’t mind playing COD4 with a mouse till I got used to it.
