My views on ALL of these designs are very good, and LockJaw is very original and all of them seem to be flawless. Mark - do not say anything!

My only problem may be Henry VIIIs weapon, because 750psi may be a bit too powerful for its own good. Kody built a robot called Avarice which entered a minor competition in which its axe was so powerful it broke off at the vital moment.

Terrorhurtz can smash up Hardox quite badly at 160psi - which why I think somewhere around the 220psi or 140psi is enough. My new robot The Rock is doing 200psi.
