Not using V3 for much of anything, I'd hazard a guess that SP3 > V3 would be easier becasue SP3 is slightly smaller and most of the JP's are more similiar to V3' and the general body shape is more similiar as well.

If you're doing from a realistic morph of AIko to V3, THEN things might be different.  Like I said--I don't use V3 almost at all.  I need to fix that.
