Well, we dont use the fireplace.  It doesn't get that cold here. So 
chimney gases are not a concern.   As to the wind load, a 3 band spider 
beam weighs less than 20 lb. and can be turned by a standard TV antenna 
rotor so the wind load is negligible.  The reason I went for a spider 
beam is because we have a hurricane or two here almost every year.  The 
chimney is exceedingly strong and I think the pole would bend in the 
middle before anything on the chimney was even stressed.
