I think you'll find that about the only BC pockets that you'll able access, and see what you're doing, is going to be the ones that have the pockets right in the front. You'll have a hard time seeing what's going on with any pockets that are on the side of the BC. Best thing to test this is to put the BC and your mask on, and put your second stage in your mouth, then try to get into the pockets.
My Ranger has pockets on the side as well as one almost in the center of the cumberbound. I can see into the one on the cummberbound just fine, but I can't see into the other two while diving. On the surface with just the BC on, is a different story, I can easily see into all of them. But after some practice, I can get at anything in any of them by feeling my way to what I need. The Zeagle Tech has pockets that are sold separately that are also easy to access, but it doesn't have any that are sewn onto the BC. I think joewr added one of the Tech's pockets to his QD Pro to solve his issue with pockets. Might ask him how he set it up.
