I just wanted to let everyone know that I've developed a new option for side venting on the M-Series sleds called Tri-Vents. I've done a lot of testing with these vents and they have performed well in all snow conditions and water skipping. They are made out of aluminum and finished via powder coating. Here are a few pics to give you an idea of what they are and how they look. Please see my full add in the swapmeet if you're interested in a set. Thanks.
