Accuracy is not dependent on the gun. It's only dependent on a good paint & barrel match.
While that is important, it is not the
only thing that matters.
Extreme example:
You can shoot perfect paint, through a perfect barrel with an el cheapo $50 wal-mart marker running Co2, and your accuracy -while better than stock- will still suck. You will chop paint, have freeze ups and have pressure spikes. Anything running Co2 will be inconsistent because of temperature, altitude, how much is left in the tank and shooting speed, regardless of paint and barrel. Expansion chambers can help a little, but not a lot.
Now anyone playing speedball will likely have a compressed air setup, which helps a lot,
but you still need good regulators (I like CP) for consistency, and good high flow bolt, and forced hopper so you don't chop paint, which kills accuracy.
I used a CP barrel kit, but I also played with guys who used a single .693 barrel with any paint (to tight is worse than to loose) with no problems.
I have a evil omen 2.0 and it works pretty good. If your serious I'd look into a Dye or an autcocker,
Or an ICD, Angel, Ego, Smart Parts, etc... there are lots of great markers today.
if your a back player you'll need the most accuracy possible. If your a mid or front player you could probably get away with something a bit cheaper, it all depends on your level of commitment.
This is true. I played mid or front, most hits up front happen within 20ft. Many happen within 4ft. if you bunker someone, or get bunkered.
To be honest I had alot more fun playing woodsball than speedball and it was alot cheaper. I found the best thing to do was organize huge 50vs50 mathces and play by moonlight, followed by a campfire and alchohol.
I never liked woodsball because everyone thinks they are gonna be a "sniper" (no marker/paint is
that accurate) and just find a perch and wait. The games would last for 45 minutes with only 5 minutes of action, after all the "snipers" finally give up and start moving.
