Winds, depends what I'm flying-18 gusting 25 for the 28, gusting 20 for a 172 and I don't like the 152 more than 12 kts, I find it very skittish on the roll out with any gusts. If it's a straight and steady x wind then I might rethink but it hardly ever is.
Vis 2K at low level (2K isn't much at all when you're in it...), but as someone has already said, I fly for fun so I wouldn't go in 2k. I would take off in it to return from somewhere then either go VMC on top or plough through the clag at a reasonable level. Ceiling, depends on the local area, if it's flat and farmland 800', if it's hilly/built up then I would want a fair bit more. You have to get down from a fanstop. Landing ceiling would be 500' off a precision approach.which is the limit of my IMC rating.
