I have been away from soaring for 12 years and have noticed the open class now has long wing and much shorter wing birds (JS-1C) competing. I am curious how do the 21 and 23 meter new ships keep up with the ASW-22BL's and Nimbus-4's. Are the new shorter wing gliders better overall (better L/D, better penetration ) or just better on strong days when wing loading counts more than the ability to stay in the air?
