2-pin? 4-pin? Screw-ins have a base that screws into a socket...which bulbs are you talking about? Any pics?
And no, it shouldn't make a big difference what the type of base is. Although screw-in CFs will give you less useable light than they state on the package due to re-strike and poor reflectors.
