Three words to descibe my experience with it: I LOVE IT!!!
I got it just in time for my trip to Bonaire in January. I love the clip system to hold the weight pockets in place, much more secure than the velcro was. I tested it out to the max too. I put ten lbs. per side and tried to shake those weight pockets out, and they weren't going anywhere. The PRO QD+ is the same. They actually gave the L and XL pro qd+ double weight pockets for each side, so you can hold up to 40# in the front. They also redesigned the pockets so that with the weights in there, you can still reach in and get something out of the front pocket. They also put the knife grommets on the left side of the balance and Pro QD+ so if you have one of the deep see knifes, they will fit right there. I thought that was cool. Like I said, I LOVE IT!!!
