I tend to vote for a 2U-width type of LFO because :
- a Sync-Input is quite benificial ( for those delayed vibrato type of
modulations )
- CV inputs without an attenuator ( except those keyboard input -
1V/Oct - ones ) are somewhat anoying because You need a a pot from
elsewhere and start to use (CV-) mixers all over
- a HI/LO range switch is a good investment to keep the range to be
covered by the pot to an acceptable value
