RE: limbs problem/ tiller
I think you should experiment and see for yourself. There is a limit to how far you can turn them out so find that out first. To start out I'd crank them all the way down and turn them back equally 2 turns, play around from there.
Think of the bow in a box shape. You can square a box up by pulling on opposit corners, cranking the bolts on a bow is like that. If it's square when you pull the string back the nock will travel straight through, if not it will travel at an angle causing you to compensate in some way to make up for it. Most bows, not allthese days are very square so the bolts should be turned an equal distance from thightened, out.If not something is off, most likely the rest/nock alignment. Some bows require the bolts to be different.
Before you start record where they are now so you can go back if you get into trouble. Always remember where you are and have gone. Take pictures, record. or and write things down. You'll be just fine.
