I feel laser-cutting attachment points would be the way to go towards keeping costs down and I am a huge fan of WTFix straps. I've replaced all of my MALICE clips with them and they really do keep things more streamlined and the weight savings do add up over time if you have a lot of pouches.

I'm a fan of zippers and SR buckles, as velcro wears out over time and isn't user replaceable. I'm sure you can see a pattern of my posts...trying to get design features that can stand the test of time that'll last even 20 years later if it isn't being heavily abused. A buddy of mine gave me a few of his M4 mag pouches when he was in Afghanistan and the velcro closure pretty much doesn't stick anymore due to repeated use, rendering the pouches essentially useless haha.
