There's some Marbles clones like Pachinko that I like.
there are full size clones too - you say you have big hands... go for a full size clone!!!
you'll almost definitely want some envelope generators and 'regular' lfos too...
the pico trio:
I think the layout of my Neutron strikes a good balance, it has lots of knobs but they're usable and there's actual space around them.
no idea never seen one in the flesh
if you go for the mantis & you should then you can get a bigger lpg... an optomix for example... which have more controls and better ergonomics (see below) and seem to be available again... and I'd also look to add a second vco (possibly another ona) and a better submixer(s) with controls for - possibly something modeled after the moog cp3 - adds a nice bit of grit when driven - AISynthesis Hamonic Mixer for example - I'm considering adding another 1 or 2 analog oscillators and will want to add 2 or 3 of these Harmonix mixers when I do...
The Mantis was a great recommendation, will probably go with that. The Harmonic Mixer also sounds interesting.
yeah... a Mantis was my second case - I often wonder, if I'd been able to buy a mantis 1st if I'd have been able to stick to it - I needed the space to add maths! which is an excellent module btw - particularly because it has so much educational documentation - both in videos and pdf form ('Maths Illustrated Supplement' - download it and read through it even if you don't buy one!!)
As for LPGs and stuff, what's your take on the Doepfner modules? They have a quad-VCA and a dual-LPG/VCA for example (A-101-2 and A-130-2, both have a nice layout too.)
for me the best vca has always been Veils - I have 3 of the originals... it's possible to buy clones of the mk2 version which adds features... I have a doepfer lpg - but it's the single channel 8hp one - I like it!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
