Great caliber!
I have also looked at 10mm (we have out grown our home and are very cramped, at home I game on folding tables and can't leave them set up) but I think if I go small I'll probably do 6mm just because of all the vehicles. There are some great 10mm lines out there and they are a bit more detailed than 6mm (although the newer 6mm, or are they really 8mm

are pretty good) so I think if it works for you go for it! I wouldn't hesitate to play a 10mm game given the chance.
