Unless it is extreme wind conditions, u shouldnt have any drift problems. I only shoot mechanicals for turkeys, simply cause i am more comfortable with cut on contact heads. I shoot magnus stingers, and nuge blades. Both of them shoot great, they are very durable, and at the end of the season you can mail them in and magnus will send you all new heads. I hunt a lot in north west oklahoma where the wind always blows 15 mph, and usually more than that. Wide open, varied terrain, and i have never seen that much difference in wind plaining. If you like your fixed blades and have confidence in them, i would say stick with them.
