Emu XL-7 & MP-7 User's Group

I have Protean Drums, X-Lead V2, Pure Phatt.

One more slot.

What to do?

Other gear I have:  
Alesis QS-R with Latin Expansion
Yamaha CS1x
Novation KS-4
Reason 2.5
Logic Pro (when it's released) = the soft synths

So any opinions on which ROM I should get to max out my px-7?
I'm thinking the Beat Garden one, for all the cool percussion.  But 
I'm just looking for opinions.  I basically do stuff from all kinds 
of genres, so any one of the ROMs is really an option.

So what's your favorite ROM, and why?
