I have a 163 with the texlium top sheet and use Burton Cartels and Burton Drivers set up at 15 and 5 size 27 mondo.
I also have a 158 F2 alpine that I ride with 65 and 60 angles.
Two different tools depending on the conditions.
My board is a lot softer flex than the carbon butterfly initially reviewed. I don't think softboot set ups are appropiate for that deck...but you could do it....Hardboots are the way to go if you have the carbon butterfly. I like how you can take the BX through everything with confidence. I find myself on the BX more often. I can really take all my hardbooting skills and apply it to my soft boot riding and push it just as if as was on my alpine. There is no doubt for me that the Madds are exceptional boards!
