I have always tried to specialize my fleet (AspX for exploring, types 6 and 7 for freight and mining, viper 4 for multi role, and FDL for combat) . I just love the Viper 4 and am constantly refitting it for whatever. Yesterday I bought a second Viper 4 and now have a dedicated combat version and a multi role. With how cheap these are I see no reason not to. I am already happy with the results and can now engineer the multi for different advantages than the combat boat. I know tycoons have 3 Annie's or something I just didn't think it was viable for smaller ships. I was wrong as it also helps loads with module storage. My advise is if you can't decide how to outfit these smaller ships buy 2.
