We have a 24x13' hydroswing in our old shop, put two roll up doors in our new shop with a post in the middle that when taken out creates a 40x18' hole in the end.

We have 5 guys working here in the winter, all 5 like the roll up situation better.  Its faster, and there is either a 24' or 16' hole when something comes out.  Only time we open up both doors and swing the post out is if the combine comes in during harvest. 

Each there own, they all have their plusses and minuses.  Hydroswings an excellent door, its just slow.

Good luck
