Seems to be a decent response on here to info, so I'll post a good article from Go Hunt. I think its a well written breakdown on the tuning process in a SW bow. Might help people searching in the future.
Also, I believe most if the issues with cam bearings going out are from over torquing. The axle bolts should be snugged, then backed off 1/8 -1/4 turn. I only back off 1/8, but my snug is pretty light, probably 10 inch pounds. I don't have trouble with them loosening, I think the bolts with the factory blue locktite can go in and out half dozen times anyways before you need to worry about it.

Only difference is with the centered cable guard the difference between top/bottom cams adjustment doesn't really exist. The top cam was closer the the cable roller, bottom cam further, so reaction wasn't as quick on the lower cam.
