So generally you guys think snaps are better then Velcro? I'm going to have to do some messing around with this system then and see what works and what doesn't. Brian, thanks for bringing up strap tension, that might be one of the issues I'm dealing with and I'll see if longer straps would allow more play, and Darrel and Paul thanks for the suggestions on the dual buttons and the stronger camping buttons respectively. Two buttons, one reversed, would give it more strength and I think camping, or tarp, buttons would a lot harder to undo. The buttons on my suit snap off real easily. If I take the shoulder plate and twist it 90 degrees it snaps off the shoulder straps the buttons snaps off with almost no effort.
There is still the question of what should I use to attach Velcro to my armor though? I'm really rethinking the button issue but I'll still need to reattach the Velcro on my thigh plates once I trim them down to size. Brian, you said that the Velcro has adhesive on their outer sides. Is that going to be enough to stay on the armor and stand up to normal use?
