I bought the carbon 35 a few weeks ago after I snapped a carbon 80.
I love it it is def a bit heavier than the other but the blade shape is sensational to use in my opinion and it is the same as the 80 and 100 blades in that regard.
The point about spending big on the paddle and not the board is you don't progress out of a paddle like you do a board. However... You have to buy a board that works!!! I paid less for scrappy Allwave than a shiny new Chinese board... Buy a proven shape and Dem if you can.
