A lot of people highlight the waterproofs being in the bag making it heavier. How heavy are your waterproofs? Are you using fishermen's oilskins per chance? My Nike waterproofs cost £75 for the suit, 3 years guaranteed waterproof, and they weigh about 500grams.
I prefer heavy waterproofs rather than the feeling of light ones that feel like your wearing a bin liner. Also on the bag is the brolly which adds weight to the total.
