Replying to Need help: Surface Double Times or Surface Watchlifes

Trying to decide between the double times or the watch lifes, I will be skiing 60% park 40% all mountain. The biggest issue i have is length and flex, I am 6'4" 205lbs and am worried the double times will be too short at 180cm and they have(according to the surface website) 8.0 of 10 on the flex scale compared to the[182cm length] 8.5 of 10 flex Watchlifes. Any advice is appreciated, Thank you!!!!
