The 2008 Target Catalogue is now available for download from the Easton website here:
http://www.eastonarchery.com/pdf/easton_target_08.pdf
and the Shaft Selector software and Tuning Guide seem to be back on the Software page here:
Easton Archery | Software , but they aren't clickable which is a shame.
Interesting disclaimer in tiny tiny lettering on the ProTour page of the catalogue
"The ProTour is designed for optimum performance in soft targets which allow at least 15cm of penetration. Shooting into harder targets that allow less penetration may damage ProTour and will reduce its useful life. If only hard targets are available, Easton recommends the regular X10 for both compound and recurve applications."
So now you know.
