Yes it has transformed my trail riding. At 6’3 with a 35 inch inside leg, I have to have the saddle so high to get correct pedaling efficiency (I like a slightly smaller frame). Dropping the saddle even an inch or two allows me to corner, pump, jump and manual and hell of a lot easier.
If you have two wheels on the ground most of the time and do not constantly mess about on the bike, I doubt the benefit would be as much. For someone lanky like me, who rides his bike like a bmx, it is great 😀
