Ok I have the V3 and m3 base characters the free downloads.  I am purchasing http://www.xurge3d.com/inc/sdetail/5416  the ahev body suits for m/3 and v/3.  Now my question is this:
are the V3/M3 Head & Body Morphs
http://www.daz3d.com/i.x/shop/itemdetails/-/?item=3010 a requirement to buy other poses and morphs?  For example lets say that I find an alien morph that I like real well for v3 can I just buy that figure and use it with my base figure or is the morph pack a pre-requisite?  Do you guys strongly suggestion buying the base head and body morphs? I'd like to just buy the morphs for the characters I want to change them into as oppsed to having to shell out the extra cash sorry I am confused
