RE: Windy decision
I've recently learnt to make wind my friend, a good strong STEADY breeze is a hoot to fly in and if it's strong enough (say 20mph+) you can practice zero fwd movement and even with some throttle jockying go backwards, also with planes that suffer from low speed tip stall it helps whith slower landings.
if the wind is Gusty its still great to fly in but the take off and landings can be a bit hard on the nerves.
