OP - everyone's system is different. Some people are highly carb sensitive and gain weight by simply looking at them. Others can diet on 200-300 grams of carbs per day and be ripped to shreds. I have come to realize that moderate to low/no carbs works best for me when prepping for a show. I suggest you experiment with different macro intake and see what works best for you. Just like heavy, I too lose a percentage of strength when on very low carbs but when carb intake is low, I am typically in contest prep and at that point, getting ripped/shredded is my priority whereas strength is of little concern to me.
