Pretty good work in the attack combo!
The Defense combo needs a better tip. AFAIK, Grand Ketos comes with an RS, irrespective of which version you get.
Earth Aquario W105RS would be good, but you need a track.
Stamina would be Earth Aquario AD145WD.
May you please list your parts? I am sure you can get better combos.
EDIT- Uff! Looking at your post, it seems like you are a Hasbro blader. If you battle in Hasbro stadiums, your combos are great! Except that you would need a stamina-saving attack type, which would certainly be Gravity Destroyer CH120/100MF
