You can 6p ky out of his dp on wake up. If not CH then you can continue string into pressure...but if you do land the 6p its free whatever especially near corner or close from half screen then you can land into fujin loops into knockdown without using any tension at all. But after the CH they float long enough so you can land close 5s > s fujin > k >...start loop. Sweep goes under VT everytime but not that great since the follow ups leaves you at 50/50 disadvantage but the Ky player will have the better option regardless. So better to go with either bait~hit confirm>then mixup, 6p...keep in mind the timing is very important. Just don't get greedy with the run ins after butterfly, play it safe and patient then mix things up here and there.
Also little side note about butterfly traps, chances are when the opponent notices that the butterfly trap is too far away, ex: any long combo into ON or high ON grab > Butterfly > HS fujin....is easy to catch BD and can follow up with S to make it safe if they block. Great way to close that gap between you and the opponent. Just a little note that can come in handy at times.
