As many know, I'm not a fan of Warwick (the organisation) however I've used the 40-100s on numerous 4 strings without any issue - I like them a lot.
IMO they have a nice feel, I like the tension level - I don't any experience of them feeling rough. I've just taken a set of D'Addarios off a bass because I felt that they felt rough - more so than the Warwicks I have on my Nanyo 4 string.
I bought a 5 string set for my Lakland - the only reason I haven't put them on yet is I'm looking for a 115 low B rather than the 130 which comes with the set.
I'm also a fan of the Fender 7250s - amazing VFM.
