Petzl S41AY Bucket

Haven't been underground with this yet, but here is some information I couldn't get without buying. Petzl needs to include basic dimensions in their product descriptions. I purchased the 35L version. Dimensions are 11 3/4" diameter and 21" tall. The top has a very sturdy drawstring closure that leaves a modest sized opening (1.5") in the top. The black bottom of the bucket is a very heavy material and is smooth both inside and out. The yellow sides have the smooth side in, so it looks like it will take a fair bit of abrasion on the outside without developing a leak. I'd estimate it will hold well over 300 feet of 1/2" rope. Since this pack is capable of holding lots of gear, I'd prefer to have padded shoulder straps. I'd also like to have a keeper of some sort for the loose ends of the straps so that they are out of the way when crawling with it. Nothing more annoying than putting a knee on the loose end and making a gross adjustment to the straps that needs to be undone when the passage opens up again. The zippered side pocket is a nice idea and has about a 7" long zipper, but it is completely flat inside and out. Big enough to get a Clif bar in, but that's about it. I'd prefer to have a gusset on the inside to allow putting more stuff in it. There are three loops on the inside at the top for attaching things like a rope end. One is red, one green and a wider one between them that is gray. Immediately opposite on the outside is another gray strap with 7 inches of tubing on it. Looks like a good place to clip gear, but it's on the same side as the shoulder straps. I can't see having a collection of beaners between my shoulder blades working out well. The handles are clearly designed to be used for lifting from the top. They are appropriately short to allow carrying the bag like a grocery bag. The approximately 9" W x 7" H clear pocket on the side is a nice idea, but the Velcro closure on the side doesn't extend the entire length of the opening. Another four inches of Velcro would help prevent the pocket from filling up with water and mud. I was hoping for something a few inches less in diameter, but the solid construction looks like it will hold up to some serious abuse. It won't be my everyday pack, but I look forward to using this when I need to carry a bunch of stuff underground.
