In reply to Joint:
I was a 5:10 Blanco diehard. When I couldn't get them anymore, I tried Scarpa Instinct Lace because that was what previous 5:10 Blanco wearers mostly seemed to be using. To be honest, I wish I had switched sooner. For me they are better than the Blancos.
A friend of mine though, really really prefers very flat, very stiff shoes even for overhanging rock. He swears by Sportiva TC pros.
