Another Outback owner here. I bought mine when it first came out. I was the 2nd person to buy one from our local shop. I must say that I have had trouble with mine ever since I bought it.... trouble putting it back in the case to stop shooting it!!! I really love mine.
I shot a Q2 for years before I got the Outback. I have shot the Switchbacks and for me they didn't make me want to change. I haven't shot the Drenalin yet, but I just don't see me switching from my Outback for a few more years. I think it is a great little bow.
