Yes, about weight distribution. The first 6 months after switching from the MX620, I used the 10g weight from the kit, as the MX620 is very heavy and it was more familiar. Then, for the sake of experiment, I took out a load, and I realized that without it I personally feel much more comfortable, after a session of 7 hours of play, my arm gets tired less, and in general, it seems that with a weight, the weight distribution shifts down too much.
