I am brand new to the board but have been reading on the forum for awhile now.  Hope to keep on learning from all of you.  Maybe someday I will know enough to give advice or at least pretend I know what I am doing.  Don't be fooled by my username.  My Ski Team currently consists of myself, wife as cheerleader, boat driver, and occassional skier, 8 year old son, 5 year old daughter, and 3 year old son. 

I ski in Alberta Canada and have a pretty short ski year.  I am going down to Texas to visit my brother and want to try out the double drafts on my Connelly F1 67''.  I picked the drafts up late last summer and only had one set on them before it snowed and I called it a year.  I liked the control of them but things didn't seem quite right.  Hard to tell as it was 45 degrees with whitecaps and I lost all feeling by the time I got out of the water.  I put the new drafts fairly close to where I had my Visions but I just rode my ski how it was set up from the factory.  Did I mention I have very little theoretical knowledge of skiing.

I see there is a guide on this website for my ski and was wondering if that is still the same for the drafts. 

Secondly, is that 29.125 distance for the front boot measuring from the back of the ski to the back of the binding or back of the plate.

Thirdly, do I measure the back binding as well or put it a certain distance from the front binding.  Once again is the measure from the binding or the plate.

I notice for sages giving advice it appears to be important to know my basic skiing ability.  I ski 22 off at 34-36mph and hoping to make the jump to 28 off at 34 mph this summer.

Thanks for the input.
