Actually, I think trying it on Hazama does make a difference. I dont think its possible to Haida loop Hazama outside a corner, and even so, itll be extremely unstable. And 3C is still extremely unsafe on block, so use it with caution. If your initial 5D is blocked, I think the two most practical options are either to continue into a drive string with mix-ups or to exit CR via pushing them away with d.5B or something along those lines. If you want to play it safe, try to end a blocked drive attack by pushing your opponent away, but if your opponent is reluctant or you're dictating the match, feel free to continue into a drive string of your liking. I think it's just easier to go into d.6A because under the condition it hits, the 5D will link into d.6A>d.6C...etc.
