I have casually observed two schools of thoughts. I may be completely wrong, happens a lot.
First school is that why cut more than a couple pounds, stay close to your wrestling weight or build up, usually expressed by dads that have wrestled. Mainly because they remember how awful the experience of a big cut was for them.
Second school, if their wrestler goes down a full weight class, they will be "strong" for their new lighter weight class with "smaller kids".
Where do you weigh in on this? Yes awful pun.
