I used my recent acquisition from Wandering Daisy, a vintage 8R, my second 8R, runs great, easy to operate. A week ago, the lady in our group had the Ti JetBoil Sol, pretty darn fast to boil water, never seen anything that fast. I understand that the MSR Reactor is designed to handle the wind better if that is a factor in anyones trips. A few things about both I see, the MSR only comes in one size from what I see, not a single person stove whereas the JetBoil has a nice selection of materials and sizes, both boil water fast. They make sense if more than one person or out for a week or longer considering the starting weight. The Stovie group I'm camping at Diamond Lake in Oregon later this week with, is supposed to have a rep from MSR showing and letting us use the new MSR stoves. Neat.
