TK GH starts up faster hits lower and does more damage as a combo starter.
for exchange it hits a bit later than standard GH.
it should be more info in the 101 threads I think.
Final Ultima is awesome...
here ya go.
"Aerial Gauntlet Hades" related woes
Q: I see people in General Discussion and in the Combo List refering to a TK GH. What is TK GH?
A: TK GH stands for Tiger Knee Gauntlet Hades. It refers to an aerial Gauntlet Hades performed extremely close to the ground via the command 2147B. It is a very useful technique to learn.
Q: Why? How does an aerial Gauntlet Hades differ from a grounded Gauntlet Hades?
A: Compared to its grounded counterpart, aerial Gauntlet Hades starts up faster (12 frames instead of 20), is active for longer (9 frames instead of 7), recovers faster (14 frame landing recovery instead of 15 frames + 14 frame landing recovery) and has a larger hitbox that hits both head and body attributes as opposed to just head. It can also lead into combos on a grounded opponent.
Q: If it's so much more useful than a grounded Gauntlet Hades, then why not just do Tiger Knee Gauntlet Hades all the time?
A: There are three reasons why a grounded Gauntlet Hades sees more frequent use.
1) If a grounded move isn't jump cancelable, you will not be able to cancel it into a TK Gauntlet Hades anyway.
2) Gauntlet Hades is technically active long before its hitbox extends in front of it, making the improved start-up time irrelevant against an opponent not immediately above Ragna. Because the extra height of the jump (as close to the ground as it is) means that Ragna has to be later in the swing to hit an opponent in front of him, a grounded Gauntlet Hades will hit a grounded opponent first.
3) Gauntlet Hades does more damage when grounded.
