Webtex will suit your needs just fine, not the most durable but you probably wont need to use it much.
This isn't the best place to ask what we have in our belt kit mate as the main things we need you'll never use in cadets ie; Rounds, Smoke, Mine extraction kit.
I'd suggest posting this on a cadet website or asking the adults at your cadet unit, they'll know exactly what you need to have for your weekedn exercises.
also on your webbing do you place bungies/utility straps around the pouches to attach scrim etc
depends on where you are really
I do not place bungies/utility straps around the pouches to attach scrim cause it looks shite and serves no real purpose remember the cup goes in the pouch not dangling on the outside of it !!!!!!!!!!!!!!
On my old belt kit I had bungees attached to my 3 utility pouches, but this was only so they pushed together and sat neatly. Reduces the movement and noise. If you do it though don't tie them too tight otherwise it's a right pain putting things in and out.
Never ever everever ever go anywhere without your 50m of green string!
You know, the wool stuff, it's so weak you need 50m to tie anything together, and when wet its wieght increases out of all proportion to its absorbency! you'll only only ever need it when its been in the bottom of your pouch for years and is just one loose knot, that once you have unravelled (4hrs later) you will find everyone else has wandered away bored!
