I was there today for the whole day, (I was the guy with the 1911 Blowback W/E Gas Pistol who carried the bomb and such). It was a blast.
The rentals were great, they shoot from around 300-320 and worked perfectly fine.
The refs were great, they explained all the games thoroughly. They also made sure everyone was safe and all.
It was very hard to tell which teammates were mine, but all was good.
I can't wait to go again!
