Thanks for everyone's feedback. I agree with you that there is not a bad choice to be made here.
Was starting to talk myself into going the X route but then realised Scoria (not Slag) has a black head but I feel he looks far more distinguished from the rest with a red head. Also, if I go the standard ones I can get Stomp (not Sludge) straight away and he is very clearly my favourite dinobot. Doh!![]()
