Glad to see other short Boba's; it's always handy to see what armours they go for. For my first version, everything was scratchbuilt and I scaled everything down to 95%. I'm 5'6" and have a GMH I'm currently painting up, Fettpride v4 armour (perfect sizing for me) and I plan on getting the NME jetpack which I hear is the smallest readily available kit (and one of the lightest).
I'll probably be interested in the boots at some point, especially if the soles get flattened out. ToEleven's helmet looks like a good size on you. Do you know how it compares to the GMH?
