To be honest, only a few boats are that bad in durability as a Laser wink But I don't want to start a Laser bashing thread here. So for sure it is one of the greatets boats.

Good sailmakers will sew quite equally. Have a look at your sail at the seams. For sure boats are not absolutly equal. Some my argue that 200g are imprtant, but this is fishing for excuses. Free your mind, go sailing and tune your boat to your style. That is fast and makes the difference
