Very good John. I would add, (to consider) using no flaps on takeoff. With no flaps you have better aileron control and less lifting potential on the upwind wing in a crosswind, especially with gusty winds. If you really like flaps 15 for takeoff then you could accelerate with flaps zero and upon reaching flying speed, have your co-pilot lower the flaps to 15. This will “pop” you off the runway. Also with zero flaps on takeoff you will be going faster so you will have more positive rudder and aileron control. Think about it, there must be a reason the POH recommends no flap landings with higher crosswinds. DO NOT forget about the effects of Density altitude on your takeoff. Bottom line - if you don’t feel comfortable, wait for better conditions. Safe flying everyone.
