Wind limits - small single engine aircraft

I was wondering what people view as their limitations in terms of wind.
I'm talking 172 / Warrior territory here.

Clearly this is a personal decision, based on your perceptions of your
own skills, the aircraft you are flying, the specific conditions on the
day (E.g. how gusty, reports of LLWS & turbulence), your risk
tolerance, etc.

But I'm interested in what the various opinions are. How much wind is
too much to fly, for you? And how much crosswind component? Does your
max crosswind component vary with windspeed? And how about how gusty it
is? Clearly if it's more gusty that's a bad thing, but how gusty is too
gusty?

Of course I have my own views on this but I'm wondering what others
think. And by the way the context is that I have decided to cancel my
flight tomorrow (Boston area) due to winds, but I'm still hoping to fly
on Sunday.

I guess as an aside, what are the scariest windy conditions you've ever
flown in? Would you do it again?

Thanks

Tom
