Those wide, protruding claws only make it slightly larger, meaning it is still small anyway.
As for the combos ,they're quite poor tbh, here's the flaws of those combos:
-Great Dragon breaks too easily in right spin, and better used in left spin. GD+SZ works though.
-HMC and 10 heavy in combo #1(wat why would you put the central-focused and heavy weight disk for smash attack in plastics when speed matters more, and HMC for attack is only for standard Smash ARs like Triple Wing, Cross Griffon and Triple Tiger and that's only when you can't control the tip.)
-Th!nk said flywheel effect and momentum affect a great deal in combo #2, and heavy weight is bad for both, so no-no, sorry, your decision to add weight just makes smash attack weak anyway (they need speed not weight)
-SG Metal Flat 2 is not good for Hyper-aggresive Smash ARs like Screw Zeus setups, so stick to standard smash attack (Triple Wing, Cross Griffon, and Triple Tiger in right, while G Upper, Eight Spiker, Cross Spiker and Panther Head in left) if you want to use it. Hyper-aggresive Smash ARs need recoil control, not survival (they have low survival anyway) and SG MF2 only increases survival, not much movement speed (compared to Uriel 2's tip, or Seaborg
