actually, I like the 19 better without armour. i have it on one of my 19's, but only because I bought the damn thing, so I should get value for it (Actually it was a birthday present, but u get the point). WHile in Battroid i dont mind it, I think it ruins the sleekness of the 19's fighter mode completely.
As for the 0 reactive: While the GBP armour is everywehre it's true, I think it was so expenaive because of how much amrour u get for your money. The reactive armour is much sleeker and smaller, so it wont cost as much.
