With the Sword Strap build you'd be looking at 100.5TP after 4 hits and a Stardiver where all of the hits connect. Assuming you have at least 1~3/tic regain it should be fine. Outside of that, you can add Misuuchi Kappa to your TP set to allow you to miss two hits on Stardiver and retain your 5hit.
Something like this should be near optimal for TP:
+1 Abjuration Tekko over Brego ofc, but since those aren't realistic I didn't include them. Ghillie earring if you need the accuracy, though on anything you'd be using polearm on (fodder mostly) you probably don't need it. NQ Phos/Bullwhip would be fine for the waist too.
For Stardiver:
Should be good.
