I love being online. Payout towing is a great way to get some miles and a great way to get some landing practice.
After trying various techniques to maximize a tow in a limited amount of tow lane, I have come to a conclusion. Mountains are rare hard to find sites but so are tow lanes. You can try to maximize a tow on a short lane, but the easiest, simplest way to safely, consistently reach altitudes of +1500ft without circuit tows or weaklink breaking pressure is to find a long tow lane.
Hearne is 7000ft. I find this to be a perfect starting point. I have climbed out of shorter (1 mile) tow lanes like Wells Lane, but it is much more difficult. With a mile tow lane, I find it difficult to get over 1000ft.
In 2012, I plan on hitting some long tow lanes. There is a 2 mile lane near Corpus Christi, Big Spring is 8800ft, Hobbs close to 10,000ft. Ft Davis and Van Horn have several lanes in the multi-mile range.
Here is a look from the tow vehicle from earlier this year.
