i dont know much about vapours, but 6mm hardox is a too thick for something with 27kg weapon. Zenith looks overweight to me, but you'd have to ask some of the more experienced vapourboteers. 15mm GC isa bit too much as well, you could drop it to 5-10mm. Trance im not sure about, lower the ground clearance and maybe up the CO2 pressure to 1000PSI?
