Ok, wow. What a blast. 12 of us met at about 9:30 am. The weather was in the high 80's which turned out to be a bit too hot later in the day, but we played on the shaded fields and took our time. It was amazing fun, we had a great ref. and a great group of guys playing.
I purchased an Invision i3 mask, neckguard, and a paint tube holster. As well as a new pair of digital BDUs from my local Army Navy store. I also took an old rucksack with a couple of water bottles and some energy bars, as well as bug spray and some old t-shirt converted towels.
I read a tip on the PBnation boards that suggested tucking a towel into your belt to protect your boys. That tip sounded much more reasonable to me that running around all day pinching my buddies in a cup. With an old t-shirt doubled up + underwear + BDU's I think it offered the best balance between mobility and protection.
As with most activities in my life I got hit in the head more than anywhere else. My very first paintball hit me square in side of the neck. The neck guard paid for itself on that hit, I highly recommend one! I got hit two other times in the head but those look much worse than they actually feel. I had two other hits on my body. Considering how some of the guys looked at the end of the day I was lucky. Of the entire group we had two hits that opened skin and one tennis ball sized lump on the arse.
We played 6 v. 6 and it was pretty evenly balanced. Our team lost the first few maps to some nasty flanking by the opposing team. We paired up after that and moved together and constantly updated each other on the enemy location. The other team didn't work together after the initial plan phase and that ended up being their weak spot.
If I had anything to change I'd work less on my cardio and more on my quad and upper leg stretches. We're all walking funny due to all the sprint and crouching. I'd also carry more water probably.
Thanks for all the comments and suggestions they were very helpful.
