Seems everyone beat me to it.
Tempe is a very nice field. VERY close up and in your face action. As birdman said, there's half-price play every Wednesday (12-5) and Thursday (5-10). Myself, Exarach, Old Dog, and a few others are regulars there on Thursdays. Check out the full hours and rules here:
http://www.tempepaintball.com/AIRSOFT.php Even if your gun shoots over the limit, TPB has downgraded springs to get it to the 350 limit (along with a lot of other airsoft essentials) and I always have my tool kit in my rifle case, so I you're more than welcome to use them.
As Old Dog said, Exarach makes excellent Hicapas GBBs (in both combat and competition configurations). PM him on there on the boards about a build or come on down to TPB and talk to him about it.
As tyedye said, the FOR SALE section is a great place to start rebuilding your arsenal and kit. There's always some good stuff up there for a good price. PM me if you're in need of some BDUs or some gear. I've got a few things I need to get rid of.
All that said, glad to have you aboard. Field games are going to start up here in a couple of months, so there's going to be some nice outdoor play as well as CQB. We're a little different than Hawaii, but we've got some very nice places to play around here.
Keep an eye out on the RSVP section to see what's going on.
Welcome and look forward to playing with you soon!
