Don't forget about all the other supplies... elastic of various sizes, a ton of snaps, E-6000 glue, plastic or webbing for snap plates, paint for your ab buttons and maybe your helmet, some velcro possibly, rare earth magnets and/or spring clamps, lots and lots of blue painters tape for fittings, exacto knife, lexan plastic scissors, and a drill.
With RT-MOD you probably don't need a dremel because it is mostly pre-trimmed but I trimmed my forearms and biceps down. Someday I'll do my thighs too.
