RE: limb tightness?
squirrel is actually pretty close. You do need to check your tiller. In case you don't know, that's the distance form the limb where it meets the limb pocket in a straight line to the string. Those need to be the same, top and bottom limbs. I wouldn't crank them quite all the way down, though. I would turn them back about 1/2 turn from being bottomed out.
