I know it's the popular answer, but Ollie and Dynasty is really my answer. Trust me, I'm not jumping on a bandwagon here.
At first I didn't like Dynasty. I continued to watch but never wanted to like them. I couldn't help it though. They seem to have plenty of fun and they really embody the sport at the moment--a bunch of young guys who are at the cutting edge and are really the future hall of famers of the sport. Kind of like how paintball is on the cusp of something.
Of them all, Ollie just continues to impress me. The others are great too, but Ollie just seems to always have it together.
Second favorite? Rich Telford and the Ironmen.
