When I am going to cruise groomers for the day, I would normally run my Arbor Woodie 163 with Drake ltd bindings. They have adjustable baseplates that adjust the stiffness, usually adjusted to be their stiffest. My stance is usually set back slightly and both bindings at positive degrees (+21f,+18b).
For an all mountain day, usually my Smokin Superpark 156 or Forum Destroyer 157, both are fitted with Burton P1's, that are medium flex and are good for everything. My stance on these two boards are setup with a wide stance(20"+) and bindings are set duck stance (+18f,-9b).
For a park day, I ride an Arbor Rogue Status 155 with Burton Cartels, set center, about 22"+ wide, with duck stance (+12f,-9b). The Cartels have a little more flex than my P1's.
Over the years, i have found myself almost exclusively running - degrees on my back binding(duck).Also, +12 front -9back, seems to be where I am most comfortable.While running a duck stance, I cannot slice that perfect carve like I can with + front and back stance.
I could run just one board throughout the season, but I choose to use multiple boards, bindings, boots, and outerwear because snowboarding is a passion of mine that will cease to exist only after I pass on. SNOWBOARDER FOR LIFE!!!!
