Hi guys,
Anyone has any experience with the ATS bmcl? How are them? Breathing good enough?
Also, i have two small 0.85l bottles on my backplate (one side for drysuite, the other as oxy backup). Maybe they'll give me some problems, compressing the bmcl. Or not?
Should i put a spacer between bmcl and backplate to add some space for lungs?

Cheers,
