I bought a set of 90-19w for my ibanez src6. It's a very strange instrument as it's a cross between an bass and guitar with a 30" scale length and therefore needs a very hard to find set of strings.
The Winspear set I bought are perfect, far better guage than anything I've tried before. Strings that other companies offer are either too heavy on the top and are hard to bend or they are too thin and short baritone strings.
The 90-19w set is great. I can get both great tones treating my instrument like either a bass or a down tuned guitar with these Winspear strings. It covered all the sounds I want with perfect playability.
Even if we ignore the vast range of string guages available, the strings themselves feel superior build quality to other strings I have used. I will now be buying from Winspear for my standard tuned guitar and my bassVI styled instrument. The pelectrum I bought is good too. It's a shame there are not any strings available here for regular scale 4 or 5 string basses.
