I have to agree with mddolson, the volo's definitely reduce air consumption. My GF switched to volos last year, before this she would normally come up with about 10 bar less than me, afterwards she had 10 bar more, this has happened dive after dive in differing conditions. It is not BS.
Dont know about the apollos have heard similar stories of less air consumption, my boss has a pair and since he got them he is definitely lower on air consumption, although watching him turn in tight spaces looks a bit pathetic, good bye viz
