Congrats on the Patriot, sounds like you made a good decision buying on 05 at a much reduced price. Whatever you paid it was worth it.
I know you still want a switchback, but after shooting your Patriot for a while you may change your mind. I tried out a SB when they first came out and there's no way it was going to "replace" my Patriot. Too close to the same machine for the switch. In my arms the Pat draws easier too.

I put an STS & no-peep on mine last summer and was able to remove all the "stuff" from the string. Now she only has a loop and is still quieter than most out there. I even had a new Trykon owner shoot it & comment how nice it was and the wished he's of shot one before he ruled out Bowtech.
