Should I bother with Stunning Fist when splashing two levels of monk on a str-based build? Assume, say, 20 or so wisdom at lvl 20. On one hand, stunning anything is good and yes I'll have Stunning Blow as well. On the other, I wonder if 20 wisdom will do much of anything for me at endgame with Fist.

Would the feat slot be wasted on Stunning Fist, or would I be better off with a different feat?
