I've never heard anything bad from anyone who has run the Altimax. I've never heard anything bad about the GYTT either, just a little too flat bottomed for my likes.
TJ has an awesome looking run flat, "Kumho SPT XRT". This thing looks great on his bike and he says it's the best handling CT he's tried. I just want a 60 series and the Kumho is only available in 55 series.
Thanks GOOSE
For those who may be interested in the Kumho...

And the old proven Altimax...
