Not sure what you intend to use the bow for. If it is a hunting only bow, then I would say you should look at the Whisker Biscuit. Less than a year ago, I would not have ever suggested one, thinking they would cost accuracy and fletching. I have since learned that it makes a big difference when you trim the back flat as they show on their web site. I am shooting as accurately with the Biscuit rests as with any other rests that I have used.
That said, I have also used the Trophy Taker, Muzzy Zero Effect, GKF Starhunter, and the NAP Plungerest Low Profile. They are all great rests. The drop aways do take fletch clearance out of the equation. I' m just not convinced that they are necessary, especially the way I am shooting with the Biscuit right now.
I forgot to say that I agree with a previous post. Get the Aluminum Biscuit if you are shooting ICS size carbons.
