I am using Inno 140B braided core ones. They speak well with the bow with a rich sound. For me, much richer than Spiros. I have no experience with Evahs, but have never felt the need to look at them. I am happy with the Innos. They give a nice warm pizz with a meaty thud. Not Gut-esque but no metal Spiro boing. I realise that these are my opinions and not empirical facts
