Butcher/purgatory grid on my 29er, had the same combo on my 650b jekyll , great tyres in my opinion. Had a wtb trail boss at first on the jekyll and had trouble with pinch flats. I’ve learnt my lesson over the years and stick with what I know works for me , the money I’ve lost on other tyres which I haven’t got on with far exceeds any savings I might have made .
