As most people have said the revvy sounds like it'll be good for you! They hold their value pretty well so if you do feel you need a quicker hopper you can always get a Halo later.
One other thing, personally I wouldn't use a Halo on a marker that doesn't have some form of anti chop device, be that an aye, cops, level 10 or other mechanical form such as low pressure, simply because if you do chop with the halo it can be a real mess to clean if the paint gets up the feed tube and into the catch cup. This will effectivley take you out the game!
