RT would work for you. I believe you should look at some (TM)EIB application's with your height and see how they look. Weight isn't your problem I'm guessing. I have RT for the width I'm broad shouldered at can say Rob makes a great sturdy kit and his helmet is made bigger to match armor better. I don't own TM, Yet. But will one day as it is a killer set. I've drooled up close. I think he offers taller shins but I'm not 100% on that. So don't hold me over a Sarlac Pit. Either way,
Good Luck Future Trooper!
