like slick said, i have a billetenium 7 way adjustable, on the lowest setting you can hardly tell it is on there, till you hit a rut/rock/log and it does it's job by keeping the bars from getting ripped out of your hands
on the 7th setting it is more of a chore to turn the bars then usual, but nothing will rip them outta your hands
i adjust the setting for the terrain, sometimes on the fly, just reach down and give it a few clicks one way or the other.
tight turn trails with little debri, i usually run in the middle, straighter rocky sh*t i run it maxed out at 7
what i have really learned from running it, is that you don't grab the bars, your hands just rest on them, and instead of pulling the bar the direction you wanna go, you push with the opposite hand
this not having to grab, grip, and wrestle the bars is a huge advantage in hand/arm
fatigue
my 30+ years of electrical work has me borderline "carpel tunnel", and my hands used to go numb after just short rides
they never go numb anymore, because the stabilizer keeps me from having to actually grip the bars
i will never ride without one again, it makes that huge of a difference
