I've ridden the simmons for years..
they are nice for sure...but, they are about 2 lbs heavier...apples to apple comparison...that 2 lbs. slows the reaction of the front suspension even with the "flexi" quality...
also the simmons "pushes" in the corners...the powder pros carve and therefore,
one can let out the rear limiter strap and still carve more in front...while allowing the rear skid to have a more desired amount of rail angle and travel..(better in the rear!)
