i bought an FX kit because i am 6'1 and 200lbs, broad shoulders and a decent size head lol, you can make a FX kit look real close to screen accurate but it does take about 30 more hours on top of the usual 50 hours build time, i will be getting a MRCE bucket within the next few months. you want to get the armor that fits your stature. people your size the FX kit will not look good simpily because you are on the smaller side. plus with your size and you getting FX you will have to trim ALOT off on overall tallness and roundness. just take that into consideration and think it through, i thought about mine for atleast a year and just recently purchased mine. all armor fits different sizes and just so happened that the FX kit fit me best, its your armor and you do what you want 90percent of all 501st garrisons own and wear thier FX kits some bought for price and some it fit better, but almost all replaced thier bucket with either AP or MRCE. but if you ask for links and such people will help you out, check the for sale forum also.
Long live the empire,
