I realized awhile ago that it's not a very good string.
Most people don't mash out DPs every little gap they get, however for characters like Jam and Sol, with DPs that have a lot of invul. frames, it's not a good idea to use it a lot.
It's also a bad idea to throw out 6K with nothing behind it, for instance if you do CSE on oki, run up and 6HS before they're out of block stun, you can 6K freely without the worry of being DPed.
Ky's got some really good pressure, there's just quite a few holes in it, so you have to know all of them them to succeed at being aggressive.
