Is the $80 Garmin clamp also Arca clamp compatible? Shouldn’t need a pic rail for the tripod.If that's the case, then I'd go with the $80 QD mount, since it's the specialized part made to fit the XERO, and just pickup a small ARCA pic rail for your ball head on your tripod and call it a day. I didn't have any of that type of stuff laying in the scrap parts bins, or I would have tried to piece something together, as well.
