I live in Colorado.. I am new to the sport myself.. I know about 10 locals that learnd and progressed from the foil's. They all sware on the tube kites, and would not go back to foil's. Coastal shops say the bladders kites have problems with the cold... My friends say they flown in 10degrees with a 15-20below wind chill..The hardest part w/ tubes is simply blowing them up and w/ cold hands closing the fill plugs. They also say crashed kites hard and no problems.. NOW im sure there is pro's and con's to this. However my friends all say tubes...
The relaunch on snow can be easy w/ the addition of a 5th line, or depending on wich kite you have now.Yes there is much less drag on snow so you wouldnt need a huge kite but changes w/ the wind conditions.
Take a look at are local web sight. http://www.KITESNOWBOARD.com
There is a section on relaunching and how to set it up etc.. Depending on the wind conditions, they all have diff size tubes for the winds. So poss save yourself some $$$$ this trip and take the tubes..
Again just new too this but take a look at the web sight.. I dont think my advise would be bad..!
