Ashton, I've told you before to stop answering questions here. You don't know enough to do anything but mislead people and waste other people's time correcting you, so cut it out.
MF-H Duo Cygnus 230MB is the best overall combo you can make, it's not really stamina but that's the closest category I guess (we just call it balance, though it's more of a stamina/wobbler custom).
Spin stealers are for the most part overrated (though MLD CH120EWD seems to be pretty decent), I'm assuming you mean LDrago Guardian, LDrago Guardian DF105WD would probably be your best bet, but isn't really worthwhile, especially not compared to duo 230mb.
Defense: MF-H Duo Cygnus 90CS. Wing is your second best defense wheel, but you don't have any really great defense tracks. I'd use 90 over 230 for defense at the moment but depending on what height attack is commonly used at in your metagame, 230 could work better if 130-145 height attack isn't very common.
You really don't have any good attack wheels there, you could try Wing in the mode with the triangle over the 1, in MF-H Wing Pegasus S130LRF but really I wouldn't bother.
