He read some stuff about them chopping paint and if he doesn't like it he will be hard pressed to get 600 out of it.
This.
The T4 is a LTL launcher that is converted to a paintball marker. It has features that make it better suited towards the LTL role that make it not so good at paintball. Chiefly magazine issues. They don't have the locking slider so the paint is always under pressure and this can deform paint. Also issues with paint popping out of loaded mags.
It's a really nice looking marker, and I'm sure it works great with FS rounds. But with regular paint, I think the T9 is the better option. Unfortunately I just like my Tac 8 way too much and don't see myself every playing with the T9. And I have other purchases that need funding. *cough*Havoc*cough*
This is correct.
