Couple Questions from a new stringer

[Reilyx]

So I've seen the different discussions of knots and after having watched a couple videos I settled on YULitle's Parnell, however when I was tying it one time I randomly put the second loop completely beneath the first loop creating basically a single loop that wraps under itself twice. I really prefer the way it looks which is stupid I know, but I was wondering if it has any potential tension loss problems compared to an actual Wilson or Parnell knot?

Also, is there a way to prevent tension loss from fixed clamps pulling away from the grommet because of the string bed tension after releasing the pulling tension? It's not much and it doesn't happen often, I just notice them move back every so often, and I know that as long as I do it the same it shouldn't matter for my own purposes, just curious.

Just to clarify, I have done about 20 string jobs so far all just on my own racquets using poly strings since that is what I use and I don't really anticipate stringing for too many other people.

If you mean on your knot that you went through the 1st loop again without going over the string you are tying to a second time, then thats basically the so called wilson knot.
As far as the clamp drawback, some machines are more pronounced than others. For the most part, the next pull compensates for that drawback so its really insignificant.

Basically what I do is a normal half hitch, then I go over and under again but instead of coming up through the loop created by the first half-hitch I bring the string up between the loop and the grommet making it basically a half hitch that winds underneath itself twice in a row.

If you go over under through, then over under and through again, you can take the 2nd loop, and rock it back and forth to cinch it up nice and tight, without much effort. Its the purpose of that knot, as a cinched up knot like this, will not loose as much tension once the clamp is released.If done properly, the tail ends up next to the frame as the loop holds it against the frame.All your knot is a half hitch with that half hitch holding the tail against the frame. I know back in the woodie days, many stringers only used a half hitch and every so often I would see one come undone. The stringer that taught me to string back in 1968 taught me the now called Parnell knot, as back then it had no name, as the stringer that taught me that just said it was a good knot to use, as it did the job.
According to the USRSA, any knot is acceptable that holds.

BTW, welcome to the TT forums. It is a nice site here, with many good people that are here to help!!
