Boss highrise shorty on my 03 edge and the stocker on my 08 dragon.
I like the higher seats myself. As said, my quads and lower back take less abuse. I also feel I am that much closer to a standing position while seated if I need to get to my feet quick. I am 5'-10" and both seats seem to hit me behind my knee. I seem to lock a leg against the seat and help pull the sled over while boondocking thru trees which takes some weight off of the up hill leg allowing for a little more of a "shock absorber" on that leg for the unseen obstacles helping with maintaining control. It also helps with keeping me closer to a centered position so I am not jumping from side to side as much. Once I get tired, I do notice that I drag feet across more and occasionally catch a foot. At this point things get expensive. The other draw back is the amount of room between the seat and butt is reduced for times that the sled needs to rise up under ya to absorb something. Climbing a "bumpy" hill is for sure a drawback for the higher seats.
For me the biggest advantage with a higher seat is the reducing of the fatigue in my legs and back which allows me to maintain control throughout the day longer. Once fatigue sets in, it won't matter what height seat ya got cause things are gonna get bad either way.
Experience does play a huge role! Guys like Hardass(not a "spring chicken"
) ride very hard and expend minimal amounts of energy to maintain control of there sled. Also they are able to stay more relaxed during the technical stuff
which is a pretty big thing as far as wasted energy goes. I am still learning this caliber of riders "basic" skills, and can feel the difference with energy levels between riding all puckered up or relaxed. The higher seats,taller risers,wider boards,lefty throttles etc allow people like myself too maintain a higher amount of control with less experience with a more of a comfortable feel saving energy throughout the day.
Maybe like TRAINING wheels, definitely helps more than it hurts.
