I’m talking alpha 3 here - I use several setups for the RD - primarily you can use it as a wake up attack - if they are point blank then you’ll grab them - got me doing this in this vid, again works best of they are coming down from a jump (and not crouch cancelling
):

As you can see I grab Karin on the way down form a jump, mid crouch animation connects straight away. You can use it as you would a wake up 720 or similar, just obviously can’t be sticking out the jabs or anything.
In terms of actual setups - see this vid:

You can mix up the hurricane kicks - third round on the vid shows what i mean. Two ways of doing this - you need to know the ranges on the hurricanes, either so you go over their head and land straight behind, or so you drop straight in front. You need to activate as soon as you land. If they have ducked under, naturally they will try and punish the missed special and you can suck them straight in. Must be point blank, must be straight from the hurricane, hardly time to land.
The final ploy I use is to juggle them with a hurricane and catch them on the way back, if they air flip you can nail them as they fall backwards. Don’t have this on vid though, it’s harder to do, but if you time it right they air flip and you catch them when the crouch at the end of the jump animation. I’ll try and capture this as well and post it up on here.
Took me a while to get all the timings sorted for these, but it’s nice to unleash them mid bout. Let them fear the full meter 
Hope this helps
