Digital BW, The Print

Just ran out of UT and was wondering.. is the UT2 inkset a 
significant improvement on glossy (PSPP) over the UT set?  Which 
black would I use for glossy with the UT2 set?  Seems I've heard both 
Ebony and Photo can work on glossy with UT2.

Any rub off problems on PSPP with UT2 like I've seen with UT?

Thanks for the help,
