what is everybodys opinion of the blade type air shut off valve compared to the air cuff. I    am currently running the air cuff but we are thinking about switching to the blade type on the next truck

never seen the blade style before.  the new conform air cuff (air bladder) is a huge improvment over the steel can style.

The Conforms Air shut off is incredible i.I am changing our trucks over to these couple years they pay for them selves I have 4 on our pumps with hoses costing $1000.00
