It does depend on the conditions. Headwind I might throw a midrange (or a firebird hyzer if the headwind is really strong). Strong right to left wind I might throw a firebird spike hyzer...as strange as that sounds. Tailwind: stable putter. Strong left to right: overstable putter (zone). Low ceiling: understable mid (beat stratus). Tight gap: understable mid (beat stratus).
Flat, calm conditions with no obstacles? Stable putter. I move up to a Roc at about 250, but it's different for everyone. I just like throwing a Roc when I can, even though I can throw a putter 280-300ft.
