Please note I can't hang a bag in my basement due to height issues. Stands are too tall, and if I use a beam, every bag will have the straps at eye level. I really, really want an Outslayer Muay Thai bag, and as hard as I've tried to make it be, it just isn't meant to be. Every thread of this kind leads to a bunch of "hanging bags are so much better" posts and advice on all the different ways to hang a bag. I've read them all. I've gotten dimensions of various bags and taped up blankets to their size as a mock-up. No dice. I'm looking at the BOB, BOB XL, and Wavemaster XXL. I used to own a BOB. I hit a WM XXL at my local YMCA for a few months. I haven't seen a BOB XL. It's not a matter of which I like more, it's a matter of long term ownership. I like hitting the WM XXL the most, but I wouldn't mind either BOB. There's trade offs. In a perfect world, I'd have an Outslayer MT bag and a BOB. Which of the 3 do you think is the most reliable/longest lasting? I looked at a BOB at a local store today. It seems bigger than the one I owned, but it also seems far softer. I owned the original that had the fully closed back. Does the inner foam last a long time, or does it break down quickly? The squishiness doesn't feel reassuring. And it's a new BOB (I'm assuming), as the store opened about a month ago. There were reports of the heads coming off and/or the chins splitting. Or was that the old ones? I have some reservations about the WM XXL. I don't know how old the one I hit was and how it was treated, so maybe it was pretty old and/or abused. I could see clear indentations at common striking spots. The bag itself seemed to come unscrewed from the base during use (I always gave it a quarter turn or so every round). Hitting it with some force, there were some days I'd hear it rattle inside, and not in a good way. Perhaps there was a magic elf on staff who'd fix something inside it at night. So I ask those of you who've had these in your school - how long on average do they last, under what conditions? Any serious issues with any of them? Also - I'll fill them with sand, put stuff under them to keep them from sliding, etc. Another stupid question - if I go the BOB route, I can put a Wavemaster Powerline top on it. Any idea if Century or anyone else sells them separately, and if so how much?
