ARs Ram and half have more vibration in my experience. They both draw similar if timed/synched properly.

I really liked the AR34 w/ R.5 cams I tried..very nice bow for the moolah..needs some Sims gear..but most bows do..You probably will end up paying about the same $ after you grab some Limbsavers and whatnot for the AR (since the Hoyt comes with them)

I really liked the AR grip..nicer than the Hoyt... for my hands at least.

I would get whichever one feels best to you.
