Hey, guys - Need advice regarding my ski.

Have a 69 in. Connelly F1X w/ double boot. Am 6'2" 170 pounds. Best ever was 15 off at 32 mph. This summer have no access to a slalom course.

From the factory, the boots are centered on the middle set of mounting holes and the fin adjustment is set to 0 degrees.

Questions:

What can I expect from dialing in the binding placement and fin setting?
Will the changes be so subtle that only a real good skier would notice the benefit?
Are they significant enough that I would notice?
Is it worth my while to play around with the settings?
What is affected by changing the placement of the bindings?
What is affected by adjusting the fin to more than 0 degrees?

Thanks! - Deerfield
