My experience is that these products work better in tubeless tyres than tubed. A nail in a tubeless tyre makes a small hole which the goo finds easy to plug. The same nail in a tubed tyre often causes a split in the tube which the slime has no chance of sealing.
For the MT I use heavy duty tubes without goo and carry lighter spare tubes as well as a puncture outfit. If there are several of you with similar size wheels you dont all have to carry spares.
On the bigger Harley with tubeless I use slime and carry a spare tube on longer trips. Fortunately I've never had to use the tube at the roadside!
If you think you are too small to make a difference you have never spent the night with a mosquito.
