A lot of people have thr Nat gut around 7lbs higher than poly- seen a few people on here have stated this.
You could try a different poly, have you tried co-focus? A lot of people on here including myself really like nat/co-focus hybrid
Have you tried using gut as a cross with poly main? That should dampen the power
