Same Eagle Mike 1.5-inchers here, but unfortunately at 6'4" they make standing ergonomics much worse for me. I haven't had any isues with the cables. I must admit they do make riding in a sitting position much nicer. It's not like I ride a lot standing up. I have no plans to get rid of them.
The thing to remember with any kind of solid block risers is that they move the bars back pretty much as far as they move them up. When I stand on my KLR, my arms are pretty much straight up and down and my head is out over the bars.
I'm content with the ones I have, but were I to do it again, I think I would go with the Rox swivelling risers to allow for more adjustment options.
