i have found some latex tubing that is 1/4 id x 7/16 od x 3/32 wall thickness

my plan is to run the tarp lines through the tubing with extras inside so the tubing can stretch and secure with a knot on the tarp line and a zip ties on the outside of the tubing

do you think this tubing is too big for this or will it be ok?

what does everybody else use for tubing size?
