I am wondering if it would be possible to make my bow into a single cam bow by swapping out the top cam with a wheel? How would this change things as far as ata, bh, and let off? Would I need a different size string set? How much loss in speed would I lose? Thank you for any info you are able to give!

Well that depend on which cams you're swaping. My Cougar III has Nitrous cams, and are rated at 320 fps. With out knowing any more about your bow, real tough for me to give any conculsive information, but I'll include this link, and you can compare Cougar III's with differnt cam systems. This is the 2004 bow comparsion chart, My Cougar is a 2004, to change years, move your cursor over the "Bow Spec Databases" in the top bar, next to "DIRECTORY". Hope this will help give you an idea of what you can expect. :)

I'm pretty sure it isn't going to work as you want to do it. A single cam needs three pegs to connect the rigging. One for the cable attached to the top limb and two for the string. You have to change both the idler and the cam. I'm not sure why you want to change from the Nitrous cams as they were one of the best systems ever designed, and especially so if you use the X system.

Also, xchanging cam systems often times changes the draw weight range of the bow. Another thing you have to be careful about is the limbs themselves. Depending on just how aggressive the single cam you choose is the limbs might not hold up to the stress. That's one of the reasons Martin changed from laminated limbs for 2011.
