I would definitely suggest the new brown and black B2 biscuit, and get the QS version as well. I acutally prefer the original mounting system to the Droptine. It is much easier to make rest height adjustments and adjust the angle of the biscuit to be parallel with the string. With the drop tine, all height adjustments must be made with the nocking point on the string. The Deluxe are probably the best, since you have both vertical and horizontal adjustment built into the rest. I guess the Droptine and Deluxe might be a little bit more rugged if your bow or rest is going to get bumped around alot.
