SAM should have a true x-hit build for GKT regardless as all the good WS are one-hit. In fact, you'll wear more STP during TP than WS to allow for more powerful WS so you'd have a little bit of overflow on startup/weapon swap. TP Bonus is applied during 2hr because of the way each WS is calculated: first WS is calculated as a 300TP WS, second is 200, third is 100. Hagun won't affect the first WS (since it won't let you exceed 300TP), but it'll affect the other two. TP bonus isn't applied during Sekkanoki though.
