I run a mix of both clamps. All I'll say is with the screw type make sure to tighten them down after installing everything! That way if you can't get to it now you can fix it.
Very good point!
Yes.... I am concerned about being able to get to some of those hose with a screw clamp. I'm thinking that it will be a good idea to make sure to get the screw clamps with the hex heads so if I had trouble getting to it I could snake a little 1/4" drive flex extension & socket to it.
