Constructively speaking; it appears you are trying to correct problems that may be caused by a flawed shooting form and/or improper installed and/or tuned gear by simply using and/or installing different accessories. It does not work that way.
As for your arrow
lifting from the rest; if you are finger-shooting, most likely you are curling too much of your fingers around the string and applying excessive finger pressure (squeezing) on the nock-end of the arrow.
If you are using a mechanical release, and the arrow is actually
lifting from the rest when you draw, that is a new one to me ……( I can hear the gasps in the background and a rapid rush to the keyboards

). However, as not to disappoint my opposition

, I will theorize and wait for someone to submit facts.
I can only theorize that you may have a short ATA bow (narrow " V" ) or a draw that is too long, and somehow, either caused by improper bow adjustment or something you are doing when you draw, your release is somehow applying an upward pressure
against the nock of your arrow, causing the entire shaft to lift. Hope someone does know, I am curious.
As for the " WB" rest; those that use the rest swear by them, and that is a personal call. However, when a " WB" user claims that the rest is easy to setup, that is a horse of a different color. I guess it depends on what the user is comparing the " WB" rest with.
If the user is claiming that setting up and tuning the " WB" is as easy as a standard rest having a windage, elevation and tension adjustment, " No Way, José!" That song can be sung until hell freezes over and will never make the top 40.
Use the " Search" feature and type in " whisker biscuit." Read the multiple posts regarding the various " cut and pluck" steps you have to perform. Consider: if you " cut and pluck" incorrectly or remove too many bristles, you have to order and install a new batch of bristles (or cut down an old poly paint brush you no longer need), and start over. You decide if you are ready and presently skilled enough to tackle that chore! Of course, if you get one and decide you do not like it, you can use it to clean the posts on your car battery.
