Spyder SE

[Crackerjack Kid]

i got a spyder SE from my brother-in-law in mint condition and would like to know if there are any upgrades i can get for it.

electronic trigger
if i can change it over to HPA, for some reason it wont hold high pressure air, only CO2.

it will be my second gun cuz i'm running an x7 phenom for woodsball, but would like something for speedball, or whatever u call the inflatable fields.
As you can tell i'm a noob to the sport, so any info will be much appreciated.
