I run my #2 tiller on my 149. She'll snort when I hit some hard spots. I don't have the hard clay-type stuff that Matt did. No weights needed. I like running with the hydro, but that's my preference. The main reason I like the 149 is the hydro lift. That's the cat's meow compared to the armstrong lift.
Those tillers are heavy. You'd be better off with a spring assist on the 122 if you go that route. Good luck and keep us posted on what you decide.
