If you want to see what Tyler looks like at his best then Blackhearted's promo renders are a good place to start. (I haven't used him in anger yet, as I got too depressed with the foreskin problem and sulked. ;) )

I find M4 squashy and rather unpleasant.... although I've got a few characters for him more recently that have been great improvements and made M4 a bit less of a doughball. I can still only stand him if he's well covered in armour. LOL.
