Training
Well i would run my practice/training days from a paintball site!
This should mean you can train all day safely, and possibly, catch a few new members.
You might also find the site operator, could sponsor you!!
You need to do more than just play.
Drills are more important, and you will learn faster.
One other thing, try and get some other local team to practice against. If they are better than you, watch and learn from them.
