You either like them or you don't
They're very reliable guns and can be shot insanely fast, however the limit of that is that you have to have the feel for them to be able to utilize their abilities. There's a certain touch to shooting an RT trigger; it can be learned quickly but if you're used to a different trigger type like a Cocker or electro then it's a hard thing to get into, making you skip shots and/or chop paint constantly instead of sending all the massive volume of paint downrange.
Get an adjustable tank if you feel the itch to, but really such isn't necessary. DOUBLE TRIGGER IS A MUST. Not only does it make it easier to learn the trigger to not chop, but it gives you that double trigger hump that you can just tickle with the tip of your fingers to unleash the full fury. Trust me, an RT without a double trigger is like a woman without a tongue or other essential parts: nice to look at and kinda fun sometimes, but you just can't get into it cause you know something major is missing.
