R/T and Cyclone feed

Hey guys I have a question and I don't know anyone who can answer it. I have a 98 custom with a response trigger installed. I wanted to know if I can install the new cyclone feed without trouble or if I'd have to buy the e-trigger.

If you have a newer 98c I believe it has 2 ports for r/s and cyclone but I may be mistaken.  I just installed a cyclone on my 98c pro with r/s and it is a dream.  No more having to shake my hopper.  Incidentally my cyclone did not come with a tee, you had to contact tippmann to get one.

The only problem I had was on the odd occasion the act system would engage the cyclone would grind up a ball.  But that doesn't happen often (I was using older cheap paint and had a ball get stuck in the breach).

do you need an expansion chamber i know they're nice to have but i figure since your using a lot more co2 you might have more problems with it
