Hey all...we have recommended quite frequently using the LONG NECKS on 5 strings Warwicks as the tapered end will work nicely with their types of bridge set-ups.
Or if you wish, you could custom order a regular HI BEAM or LO RIDER 4 string with a tapered B. Many US retailers order them from us like that, and we consider it a 'custom' set, though we don't charge any extra for doing that.
Hope that helps.

Is there really a difference between the Lo-riders and the Long Necks other than the fact that Long Necks are longer and come with a tapered B?
