How to I optimize my opener and rotation as Samurai?

In a perfect scenario against the susy ex dummy I have 3 sen as the Hagakure comes up. So I will typically Hagakure these sen and move into the Meikyo for a Midare. In actual fights its not always so ideal. Generally speaking I will prioritize the Hagakure by using the Meikyo to fill up any missing sen and if I have uses of Meikyo after a 3 sen Hagakure I will use them on whatever sen has the longest time left on its buff.

Interesting... So even if you have 1 or 2 sen, you will use Meikyo to fill up to 3 and use Hagakure anyways? Don't you feel like that's a waste of Meikyo? The CD on it is double that of Hagakure so I've been treating it like I HAVE to use it for a good Midare lineup.

EDIT: Also, when do you guys use your strength potions?? When is it most optimal?

Yes, because Shinten is a more efficient use of the Kenki than a Keitan Midare. I dont have a link to the math for that on hand, but it has been accepted by most serious theory crafters that I am aware of. Also as Adriosh pointed out if you already have 1 or 2 sen when Meikyo becomes available you can use it to get the ones you need, Hagakure, then use the rest of your Meikyo uses to fill sen slots back up.

Most str pot rotations I have seen prioritize it before the Gekko or after the 4th GCD.
