MOTM

Due to the excessive length of the Blacet Time Machine (won't fit it my
SKB popup) and a few other factors I'm building a portable cabinet to
hold a keyboard, joystick, and one row of modules.  In this case one row
is going to be 15 U.  Of course you can never have all the modules you
want, even more so when you have to fit them into 15U.  So I now need to
decide what modules I'm going to put into this case and which will be
relegated to the SKB as an expander.  I've got a pretty good idea of
what essentials I want to house, but  there are some issues I'd be happy
to hear opinions on.  Here's the list of modules I'm pretty set on.

Encore UEG = 2 spaces
Blacet TM = 2 spaces
EG x3 = 3 spaces
uVCA = 1 space
QLFO = 1 space
1 300 VCO = 2 space
VCF of some sort = 1 or 2 spaces.

1 300 VCO + 2 310 uVCO or 2 300 VCO? 
I like to do FM stuff which makes sine out of 2 oscillators desirable,
but an extra VCO is always nice.

Which VCF?  I have a uVCF which is fine, but the 420 or 480 seem more
versatile.

In order to make room I could drop one EG, since the UEG can be used for
EG functions as well as step seq.  That would allow 2x300, 1x310, and a
2 space VCF.

Opinions?
