Before useing a Schweizer tow rig give serious consideration to the
info on this website
http://home.att.net/~jdburch/index.htm
I too would reccommend a tost tow rig only. Far safer for both the tow
pilot and glider.
NTSB stats show on average one tow pilot death each year- upsets on
tow with no chance of recovery.
I think the FAA data is way out of date and should have been revisited
long ago.
Good luck
