I have a 42 scale bass I use for classical and was wondering if you tried Spiro weich E A with Flexocore 92 D and G. Didn't miss any bottom end with the weichs and they felt good under the fingers. Flexocore 92s sounded good but a little tight on this bass so switched to Belcanto G and D. Thinking Flex 92 D G might be better on your bass.
