If I had a PSE Nova, and I have set up a bunch of em, I would get a Muzzy Zero Effect. Best "hunting" rest there is. Worked great with the older bows like your nova, that had tons of cable slide movement. Just worked like crap for parralel limbed bows like the modern ones because they have very little cable side movement.

They can be got for less than 35 dollars now. I have had 3 of em, but I paid over 100 for em back in 2000 and 2002.
