One good thing with the D/F+1,2 D/B+2,2,2,2,2 is that after a few slaps you might be able to go into D/B+1+2, 1, FC F/D+1, U+3+4, U/F+4, U/F+3, SS(anymove) or even a grab(from Tenshimitsu!) I tried it today and I figured that its pretty flexible and can make your opponent pressured since they don't know what you are gonna do.
If you do sword sweep a lot after the D/F+1,2 D/B+2,2,2,2,2 combo you can try a flea so if they try and hit low they get damaged.
Yes, its probably unsafe to do those moves but for me... I don't look at frame advantages because I'm a NOOOOOOOOOB.
