please help me with a knot

i want to make a rig the same length every time. i have my wood with the two nails in it
now what kont do i tye so when i finish the rig it stays the same length?

How about a uni knot, form the loop over a wooden dowel so the knot comes out the same ( in theory) every time.

I tried a different method some time ago to get snoods the same length for rigs, I tried using some tubing, put the snood through the tube, through the hook , back through the tube, pull the rig tight to the right length, add a blob of glue & slide the tube down to the hook eye over the glue.

I had 50/50 success with this as some held & some didnt as the water released the glue.

The problem is finding a bonding agent thats water proof, can be applied in small drops & sticks to mono & the tube material as most super glues dont.

the best one i have found to work so far is the PALOMAR KNOT but i would like a smaller not

is this the best?

palomar for rig ends ie top swivel and quick link to lead and for hook lengths uni knot or tucked blood knot but at the end of the day use a knot that your happy tying up and have confidence in
