DS2:Basing elements

Dear DS2 players

I'm new to DS2 and have not played a game yet.	I have for some time
however, been slowly painting up around 50 elements to get me started. 
I
can't remember if there was good reason why I started using my current
basing convention, but I have been using 1.5cm plastic card squares for
both
infantry and vehicles.	Large tanks/trucks etc get a base that fits
their
mass. 

I have been noticing many pics on the web of DS2 games and GZG
conventions
where vehicles are not based but can be deployed very close together. 
As my
units would have a minimim of 1cm plus easement between them, would I be
at
a tactical disadvantage on the battle field playing someone who does not
uses bases and can place their units 'en haye'?  More than happy to
email a
few pics to anyone interested in seeing what I have done.

I probably based my units out of habit as well as having the view to
protecting the paint jobs as well.  Any advice appreciated.

regards
Dave Tan
