I started at 20, I am now 47. I've always used pistols only, my preference for the .50 cal 3357 pushed me to avoid FPO with outllaw play for a long time except the occasional visit to HS. In 01 68cal pistols started appearing and I rejoined the paintball world.
I'm lucky enough to live near Hell Survivors, playing all pistol at their big games is a real challenge.
In 05 they started using neck ID tags with barcodes. I've lost a few tags and missed one big game since but here's my pistol big games and tourneys since 2005(we call it Hell Survivors Solitaire!):
I love it as much today as ever!
I would say I'm a much better player now.
