the q2xl was my first brand new bow purchase. Its an awesome shooter. I also had a drenalin and never meshed with it the same way, I wish I had gotten the LD after having opportunity to spend some time behind that bow its awesome as well. Obviously they are very similar. Its been some time, but my impression was always that the XL felt like I couldn't miss, while the LD was a a little more vibration free and picked up a smidge of speed. Both bows are very smooth, forgiving, aim like lasers. and tune well. Personally I would shop for a drenalin and pick up whichever one came along first that fit my parameters.
