Cave diving sidemount means you only have to carry one tank at a time. But boat diving to get to wrecks? Assume worst case. You strap on a pair of HP100 and giant stride into the water. And they immediately issue the diver recall signal. Consider the mechanics of how you are going to hand up to the crew at the top of the ladder a pair of full HP100s when you are bobbing around in 2 -3 ft waves. Is that possible and safe for you to do? Or are you going to be climbing the ladder with them attached?
I'll discuss that with instructor and/or friends who dive the Lakes SM.
Heck, my LDS owner has dove the Lakes SM. There's a picture of him diving SM on the Hume hanging in the store.
I really should go through the thread and tally up the votes for, against, and "you're freakin' out of your mind" on SM on the Great Lakes.
