Interesting to see you guys skipping the 120 bottle. Something we've been considering here as well, as the min gas just starts to get insane with only a 120 bottle, but if you bring the 120 as well, it just seems to get into bottle hell.
John and I did a training dive for this a few weeks ago. It was already like tubular bells going down the shotline with all the AL80's. I had 3 AL80s and 2 AL7s for most of the dive, and this is for 20 mins at 330 feet. As John Says, we then have bottles being delivered just in case by support teams at 24 metres and 9 metres.
