I'm biased toward axis just because I'm a coach for them. But both programs are solid. The coaches for Fly aren't as popular on NS, but are still good coaches.
The coaches for Axis are...
Most of the SLC 4bi9 crew...John Kutcher, Tim Maney, AJ Dakoulas, Ryan Wyble And then Wiley Miller, Tim McChesney, Luke Perin, as well as others.
I dunno the differences between the amount of time spent on ramps/tramps between Fly and Axis, but if you have any specific questions about Axis I could probably help answer them.
