Theres no wind in Kansas, Cat. Well at least no more than 70 mph most days from my experience. So a boomless sprayer may not be as appropriate. But better watch opinions of Mennoniteman as I bet he likes tree tubes over cages also!!
Anyways, the Fimco uses inline water hose type filters that I had problems with the chemical plugging up requires me disassembling, and getting dowsed with that crap. Also the pick up line is poor especially for those of us who navigate hillside plots, maybe not a problem for you. And for whatever reason, once fluids got low, mine refused to pick up remaining solution. The drain hole takes forever to drain remaining solution and the water you are rinsing out the sprayer after using. I modified a lot of things on mine and it obviously used it for 8 years I think, but I had to go to church many a Sunday to compensate for my mutterings while using it. For the money, not bad. TS carries most the parts in large stock (that should tell you something).
As for boomless, just convenient for trail use, not gonna argue. boom may be more efficient . But added benefit for me is managing one sprayer/boomless is sure easier than my lazy ass managing a dozen on a boom.
