The 3" forearm of the EDGE can be used with any standard front bag. The buttsrock might work slightly better with a 2-stitch rear bag but I have used them with both. Of the rear bags, I prefer the rabbit ear Cordura as opposed to to a bunny ear leather. But take your choice, folks use all 4 designs.
What front and rear bag gives really good tracking with these stocks. I picked up a use BR rifle with this stock and wanted to order some bags for when it arrives. FWIW I'm using a caldwell br front rest for now, I'll be upgrading to a shade tree coax top soon enough.
David, it seems that stocks with the completely vertical sides, like the EDGE, are more sensative to side pressure.I have heard repeatedly is that Edge stocks tend to be sensitive to front bag tension. They don't seem to like a lot of side pressure
