Have I ever shot a Pearson with Vib-X you ask. Why yes my lad. I was a staff shooter for them for 4 years and in 2003 I repped their products. Damned fine ones at that.

As for passing on by if I don't have a clue. The only reason I'd have a clue about the limb pockets is because I'd take a look and then take an action. That's how I learned about being a bow technician. Me and about 99% of the other people that work on bows. We just learned by doing. These things aren't hard. They are sometimes a little different from bow to bow, but the basic mechanics are all the same.

OK, for simplicity sake. The side bolts lock the limb pockets in place. To adjust the weight just loosen the lock bolt, adjust to the weight you like and then lock it up again. Just like a Hoyt and several other bows.
