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

I have been toying around with the FX settings on my XL7 all day and 
I've come to a decision on *how* to route them, but now I need to 
choose which ones to use.  I've settled on running in multi mode and 
having a 'control' preset on channel 16B, routing all the FX sends to 
knobs.  This way I can not only control the FX sends in real time, 
but also switch that MIDI channel to other FX setups stored on other 
presets.  So my question is this:  What are the two most useful FX on 
the command stations?  I've been pretty much using Delay on my FXA 
and Distortion2 on my FXB....  What does the forum think?  The more 
general use I can get out of them the better.
