Baldigus is definitely tight all round. Shuttler seems mostly fixed compared to Blastoff. Hepter(or whatever the US names are) is using the fixed HFG port. Dolrailer has those modified hip-locks Megatronia uses.
I think the possible problems you may encounter are paint issues. Mine has a small blemish on the chestplate, see if you can spot it.
