I never move my saddle on the MFS as the sus allows me to stay seated for more of the time and to keep on pedalling going faster and faster!
But thats my point , your just letting the bike do the riding for you , all you do is steer . The reason i say lower the seat is to learn to move around the bike , manipulate it ; take the board out of your back and learn to flow across the Earth .
Could you imagine lopes being as quick seated ? Or a surfer sitting down ?

Exactly the same technique can be applied to any trail .
Only time I'm seated while on the dirt is to rest ; please pass
