Paintball
I used to play paintball years ago (around 2002-2003). I was never very good, but it was fun and was a way to spent time with friends and be outdoors for the afternoon. Recently I have been playing with co-workers, and a few friends. I have two markers, a Spyder Aggressor XT and a Spyder Pilot ACS, allowing me to play and loan one to a friend. The Aggressor XT is a semi-auto while the Pilot is an electonic marker (allowing for semi, 3 shot burst, 6 shot burst and full auto). I am having fun playing with the markers and upgrading parts here and there as I break or wear out the bits and pieces. I have gotten a new barrel for the Pilot, replace o-rings on both markers, and made other repairs.
I have been really having fun. Each upgrade, or tweak to the markers improves the capabilities of the marker. Actionvillage.com is a great place to find parts, markers and other paintball equipment. If you have a Kingman Spyder, the Spyder forums are a good place to get information, and ottersccustoms.com is a good place to read up on upgrading your marker.
Even with the upgrades I wouldn’t say I have gotten any better, but I have been having fun. I think that is the most important part.
