taking a Western Saddle on Air Plane Question

I need to take a large roping western saddle with me on the airline.

I know they all charge for luggage now. I have read many comments many places:
They are not considered SPORTS equipment as many items golf clubs, skis, surf boards even, but not saddles.

IF I pack it in a large duffle bag It does fit under their weight allowance of 50 lbs and under the 62 inch max.

Any suggestions or ideas. I hate the thought of lugging that duffle bag without wheels, but it won't fit in my wheeled bag.
Thanks for comments, suggestions, ideas.
