You don't really need SHP if you use classic valve, it's more relevant if you use any of the RT type valves and want to have more reactivity.
I will get the kit. I also need to get the Tippmann O-ring kit, because one blew in my 98 Custom last time I screwed a tank in. That gun is hell to put
Thanks.. Updated it a bit.
Dono if it's good or bad...
