is there an "IDEAL" combitaion of ridge line and sliding prussics? i've read on this forum that the prussic knot/loop should be smaller than the main line.( i seem to remember that it was something like half- can't find the posting that suggested this)..this got me to thinking...if there's and ideal line dia. to do this, what about line types? i'm assuming that dislimer line types will hold better and allow me to use one size line whruout the tarp suspention system. i haven't bought any line for the tarp set up yet and would love to nail it the first time out the gate.
