Your ROI & ITM are very good. What percentage of the time you get to HU are you the chip leader? If that number mimics your results, your option is to get more aggressive on the bubble and just before the bubble, but that will tend to lower your ITM (but probably not your ROI).

In your situation, I'd be careful about trying any pre-money changes. Once HU, my only suggestiona are 1) randomize your play more and 2) try to get a better profile on your opponent before HU to see if he has any tendencies you can exploit.

Otherwise, if it ain't broke, don't fix it.
