Thanks Alan H. This is all very interesting to me. I am going to get myself a 6x6 and play around with it. I really enjoyed getting the overview of your experience in Highland Athletics...it seems like you have approached many seasons in many different ways, depending on the year.

Just out of curiosity, what do you think of Sorinex's Ballistica http://store.sorinex.com/The_Ballistica_p/bal-1.htm as a training tool? I don't know if you have used one of these or not, but maybe you have an opinion or heard something about it one way or the other... Thanks!
