Nil yes I'm also transmale and using binder from past few years, first i brought half binder it made my chest flat but, the stomach fat shifted to waist and it was looking awkward. later i choosed using full binder it was helpful.
If you are thin and no belly fat then half binder will work, if you're having belly fat and side fat then it will make uncomfortable and you can't bend feels uneasy, then you should go for full binder
