I've been told that Sea Gorgets only grant the TP modifier on the first hit of a WS. Whether that's true or not I do not know, but it appears people aren't completely concrete with Sea Gorgets and Weaponskills.
For Penta Thrust and Skewer, I use Love Torque. For Wheeling Thrust, I [would] use Flame Gorget. Shadow Gorget I would probably use for Impulse Drive if anything.
So for Penta Thrust, it's going to go:
Code:
Love Torque >> Peacock Charm >> Shadow Gorget >> Chivalrous
For Wheeling Thrust, it's going to go:
Code:
Flame Gorget >> Love Torque || Chivalrous Chain
Uhh for Wheeling, it's kind of a toss up in my opinion if you don't have a Gorget. You want to go with more STR to increase that damage cap (I found, during the absurd 2handed buff, my Wheeling Thrust capped at 1060~ on Greater Colibri and would not go higher even with SV unless I had more STR. Double Attack'd increased the number further). But it's up for grabs. Go with whatever makes you miss less often.
