As much as I hate it when Hardcase does it, glue is the easier solution, and the pouches stay tight to the body of the MOLLE platform, look good and never come loose (unless the glue goes brittle and crumbles). I on the other hand have spent literally hours, swearing like a trucker raised by sailors with Tourettes, feeding little tiny MOLLE straps through little tiny MOLLE loops. I do this simply because I can't bear the idea of not being able to take the pouches off and re-use them for a different bash.
If you are a static modeller who's going to put it up on the shelf and always be happy with it the wy it is, like Hardcase, glue 'em. If you're a OCD action figure accuracy nazi with attention deficit disorder like me, strap 'em and weave 'em.
That being said, you can make your own, do Toy Soldier-style prong clips and sew them down to your pouches. They look good, keep 'em tight, and are movable/removable. This is probably my favorite sytem of all. I find the best material to make them from is 4 liter milk jugs.
