I know flexing the wheel is to release spoke twist after truing, but squeezing parallel spokes is mainly for seating new spokes? I always tighten spokes 1/4 turn too much then back and do the same while loosening if the spokes are tight or corroded, but still I find myself going back to the method of flexing the wheel .. it gives me the feeling of being complete. I am definitely more careful since and have noticed that the wheel is actually more prone to collapse with the drive side up, which is contrary to intuition and as suggested in the second post. Anyone have ideas why this might be?
