I think it has to do with personal preference. I have a set of Army Combat Helmet pads in my bucket. I think they work great. You can find them on eBay.
I was approved with mine. Use E6000 to glue it together. Is this an AM kit? If so, start by gluing the back to the top. Then use the supplied screws to attach the face and ears. Easy.
If you're going for Centurion, according to the CRL
For level three certification (if applicable):
These shall free float in back.
These shall be glued in front.
The plastic shoulder straps need to be held down in the back via a white elastic band to the white fabric that connects/bridges the chest and back piece.
As far as attaching the belt. I made snap plates out of ABS and glued them with E6000 to my Ab. I didn't have to drill a hole.
