why not cut this weekend and see how bad it is.
I'm not kidding.
Its something to practice, just like hitting a heavy bag.
my usual take on weight cutting and I don't necessarily mean you
is that if people are complaining about cutting,
then they should find another sport.
In your case I would suggest two courses of action
work hard on conditioning cut easily to the next lowest weight class what ever your 180 something is.
or do a test run , sooner vs later, spar 2 to 3 hard rounds 12 to 24 hours after and see how you do.
honestly - I think 24 hour weigh in's are a godsend and make it a non issue.
same day weigh-ins I would tell people to man up any college wrestler can tell you
you can cut a good amount for same day weigh ins and compete right after- or they would
just find something else to do.
to put it in perspective 8 lbs in an hour for someone in good condition at about 200 lbs is very reachable.
How disciplined is your food diet situation, are you relatively lean - and eating huge to keep on size?
or are you already gram counting clean eating etc?
this is a good test - a fight that would be competitive but low pressure to do either course of action
cut just enough to make the next weight class, or use this fight , and next month to figure out
how you deal with cutting.
