JMC22

StiX already has an adjustable float collar for macro ports $65 USD

I was thinking the same, but given the weight of the MV24, I think they are recommending putting it on the rig after getting into the water - which might even be a better idea if combining with a MV60 on a triple flip - One lens you forgot in your list is the MFO-1 I would think a double flip with a MFO-1 & either a SMC-3/MFO-3 depending on the site & then put the MV24 & other in a pocket

I just returned from a Komodo - Alor trip & dove with the Manta's on Sept 4th
