I thought everything was bigger in Texas.
Blue Lake S-7 might be the BL to trial in the future. Regular BL gets to about 10-11 feet tall, here. So, it might grow up and then almost all the way back down again, for you. BL S-7 grows to about 7 feet.
In my garden it's 11' bean poles, put ~1 foot into the ground. Most of my pole bean vines get to about 14' in an average year. A poor year is about 10-12', a really good year ~20', which means all the way to the top and almost all the way back down again.
