The Midas E0 7s were also on a GS and on one of our harder riders. He loves them and switched from Heidenaus. BUT, he also reported much lower lifespan....around 6,000 to 7,000 miles where he got near 9,000 on the common radials available.
My Tenere is on the BWs it came with but I am going back to Anakee 3s when the Wings are done. I like the BWs just fine but the A3 is better in gravel and as good on the wet.
All of us had pucker moments yesterday, but mostly from wet mud in the road in curves. When the water is flowing on asphalt its hard to see a layer of thin mud under it. It is like grease. I started just standing my bike up when I saw wet spots in curves if I could. It sneaks up on you so fast if you are riding any speed at all.
BUT, the Heidenaus let loose on dry clean roadway....this is what surprised us. No braking, no throttle, just a significant lean angle.
