What are their similarities and differences?
I am 5'9" 145 lbs and looking at these in a 178.
Thanks for your input.
where do you ski? what do you like to ski? how good are you?
these ski feel much more different than alike.
a lot here...... I don't know how you ski or what your preferences are. The s7 is fine for most skiers and at 145 I would guess it would be OK for you. What size? This is a clear case for a demo. You need to figure out what you like in a ski. The Keeper is stiffer due to the construction.
