54 in wide simonton 9800 doublehung

Thanks to some research here I have decided to go with Simonton 9800 line. I have one rather large window 44.5x54 wide. Has anyone bought a single doublehung this wide? how will it hold up longterm (IE sagging, ect?) I am debating doing a 2 in 1, but it might look a bit funny as the windows will not be that wide.

thanks.

Just make sure you get sash reinforcements. Simonton will manufacture and warrant double hung windows up to 56" wide.
