QAD Drop Away rest highly recommended...
I love my single pin sight but single vs. multiple is a personal choice... I have used a Vital Bow Gear single pin and last year I switched to a Copper John Dead Nuts...
Just make sure the sight is very bright.
If you buy a Mathews get the Arrow Web Quiver... I have the 3 arrow and although I have never needed more than one arrow I sometimes wish I had gotten the 5 arrow for a few bucks more.
Stabilizers I really like my K-Tech... I have the K-Tech 5" in Lost Camo
http://www.ktechdesigns.com/jzcart/showitem.php?id=4516 and its really nice looking and does a good job... the other option I looked at was the Axion but I didn't like the Harmonic stabilizer on the front of the Stabilizer in that direction
Hope this helps you out... PM me if you have any questions or need any other advice... remember to get what you like and fits you best... don't let anyone decide for you what you like and dont like
