I posted this in the Rimfire==>Vudoo thread in answer to a request... anyway, here's my Vudoo/MPA with Atlas BT65-NC CAL ($239) with RRS BTC-Pro ARCA clamp ($70). Ordered both from Mile High. Had it in three business days. There are plenty here who will scream Heresy!!! but I don't find it all that much more solid off a bench than my Harris HBRMS bipod with Pod-Loc and the RRS HC-Pro ARCA adapter. More solid, yes. A hundred dollars' price difference more solid? Your preference may well say "yes." Or not.
Both Atlas and Harris model differentiation is pretty opaque. The Atlas BT65-NC is the CAL model with Pod-Loc as standard and no clamp at all, hence the RRS clamp.
