Future Upgrades

I would like to tell you guys what I already have on my A-5, and you tell me what else needs upgrading.  Now, having said this, I don't want Nitro/HPA and I don't want a Palmer's.  Other than that, everything is up for discussion.

My setup:

A-5 w/ Polished Internals, Trinity Spring Kit, Rufus Dawg Wicked Bolt, Dead On RVA, E-Grip, GTA Double Trigger, GTA X Chamber, Shocktech Drop Forward, Smart Parts Inline On/Off, Tapco T-6 Adjustable Stock, 32* Remote Line, 12" GTA "Sniper" Barrel, 12" Lapco Bigshot, 16" Stiffi, Flatline, Tac-Cap, and 2 Pure Energy 20 Oz CO2 Tanks.

Now obviously, some of the parts listed can't be used in conjunction with one another, but I do change my setup as the game style requires.

Yea, that trigger does look nice.  I already have a remote line, but rarely use it.  I don't want a red dot sight because if it gets hit with a paintball, it will most likely damage it (plus I like to use optics strictly on real guns because there is no point in it in paintball.  there just isn't enough accuracy).  Any word on the quality of that hopper that was mentioned?  I am very interested in the sight rail because I would love to use my stock in actual play instead of just plinking around (without mask).

edit:  What exactly does an anti- syphon do?
