Won't be at Lincoln City Summer Festival, sorry... Will be there for the Fall Festival in October however.
Dual line flying, when I retired (for the 2nd time) in 1998 I was at the top of my game... Between then and 2002 when I came back, slack line tricks (jacobs ladder, roll ups, etc) really came to North America and I didn't catch the curve... A bit stuck up, I stayed "old school" until 2005 when I picked up Lam Hoac's Sea Devil and went through Randy's tutorials one by one until I was again a force in dual line competition.
Now, I fly dual lines maybe 2-8 hours per year, spending most of my time on the Revs.
Even so, most of my quad time is spent flying team... Absolutely the most pleasurable thing I've ever done in kiting.
