Stab. and QEV Q’s

I've ordered the "Super R/T" mod from tippmann, and I'm likely going to be purchasing a palmers stab.  First of all, is the palmer-persuit shop the only place to get a palmers stab, or could I find it cheaper?

Second, why is there a QEV for the R/T at the palmer site? What effect would this have?

Lastly, would I have to order the "A-5 stabalizer" or could I simply order the male, and if so, would I need to buy new hosing anyways or could I use the hose already attached to the ASA (remove it from the part that screws into the vertical adaptor)?

Any help is appreciated :)

You can buy Stabalizers on www.countysports.com for around the cheapest you can get em' (right now the sights down though). And you can get either the A-5 kit or the Male seperate. I believe the kit just comes with a couple of fittings and a new length line, so it's your choice on what to get. If it were me, I'd purchase the Male, and get a Macro Line Kit from county also. I love being able to take the line off my marker in under 10 seconds...

There isnt a RT qev, but you need the QEV on the cyclone when using the super RT

www.paintballgateway.com has stabs pretty cheap
