Are Outer Ring commands easier or harder on SC2 due to the Touchpads placement and shape?

As someone who maps sprint for *most* games on SC1, it's great. However, I've tried using it on my Deck's (since they share the same shape and mostly position as SC2), but found myself running outta room, mostly on the top bit. It even was to the point of hitting the bottom part of the analog sticks. So, asking if this is a similar experience with SC2, and ways to make it feel better.
