I’m not sure if this is common knowledge yet but ill post anyways.
Since you can tag cancel early in the Fury Fist animation, you can actually get the charged free super with a lot of characters and for the ones ive tested it seems to be the best damage for tag cancel combo using no bar. So far I have used this with Hugo/Ryu/Marduk, and I’m sure much of the cast can do this.
For some characters it might be better to tag cancel in and do a HP or HK and then charge to an EX that has a wallbounce for a bigger combo. For example with Marduk I do cl.Hp xx charge EX tackle wallbounce c.mp , c.mp xx airgrab ; which does a little less than super but builds meter.
