I run very wide tires at very low pressures, so tubeless makes a ton of sense because the friction is felt a lot more between the tube and tire casing. If you're running 80 psi you don't have as much drag. Still makes sense to go tubeless because the hassle isn't near as bad as what everyone *****es about and now is a good time since you're changing out tires anyway, so if you have the tires + rims the extra cost isn't that high. Once you get them on there you can lower the pressure too and not have to worry as much about pinch flats. You will still have to pack a tube or get good at using bacon strips. Have fun man!
