I doubt those strips are strongly magnetic enough to hold it tight. You could experiment and let us know how it goes, but I wouldn't expect much to come of it. Velcro will probably be a better fit for the problem.
And as much as a I hate double-posting, I really should say...
My build is now finished, as I am now TK 8045.
Many thanks to all of you who helped me. And I know that though this thread might be done, the tinkering will be with you. Always.
So yeah, I also have an RT mod bias here, but I have to say no trimming made me a very, very happy man. I think it's worth the extra moolah. Assuming you haven't already made your decision.
I kind of like that beat up look. When you have dinged up spots on it, paint it all black, then detail them with a flat aluminum and some careful brush work.
Here's a pic of my Hasbro mod so you can see what I mean about detailing.
Aw shucks, you're gonna make me blush.
I'll look over your build thread again to see how you did that, it won't hurt to see if your method right now works better. Plus, it'll give me something else to tinker with, as if this hasn't cost me enough time and minor cuts with scissors. (I'm like the running joke in my family now).
I'm going to change my approach to the thighs. I'm going to put them on first now and really wiggle my hands around. I'm using industrial velcro instead of elastic and snaps (since the snaps kept breaking), so I can probably get another inch or two out of it with both of these.
I think the shoulder bells are sagging a little because they pull my webbing bridges off to the side. I don't really see any way around that one to be honest, so I may just have to deal with it.
And yes, the knee pack was bloody hard.
My big question is, is there anything here to prevent me from getting approval?
