Hello there. So I just had to break out my US calculator and it shows that you are around 5’10” and about 143LBS. Tbh you are in the perfect height range for a TK. Yes maybe a little on the thin side. So based on that I would say TM would be your best bet. And it is a super nice set of armor. AM is more geared toward the larger waist trooper and RT is geared toward the super tall trooper.
As far as putting it together, pretty much all sets of armor go together very similar this day and age. All three of those sets are top notch. I just ordered myself a new set of TM and really cannot wait for it to arrive.
