No doubt the 9 wing beats it for high XC, but KOKB (Oceanside, Ca) to KAPA (Denver, Co) and a go around and diversion to KBJC (+737 miles) in my 7 on less than 29 gallons ain?t bad. I did have more like 30+ tailwind avg for the leg. I almost built a 9 twice before I settled on the 7, you can?t go wrong with either!
