I ended up buying the feelgood ES 150 with the lexa est binding in large. The burton specs state that the 150 is for size M bindings but I had no problems putting the large on it (I wear a size 10 sapphires). No toe or heal drag at all in the 2 times Iâve tried this setup. Probably wouldnât bother putting a non est binding on this board. The conversion kit adds height & weight to the board. Kind of defeats the purpose of getting an ICS board. I tested this out on 5/2 at Squaw Valley in powder conditions (I know, I couldnât believe it either). The ICS system was so awesome because it was a cinch to push my bindings back so I could stay afloat. The whole setup felt so light even though my new board was longer than my old salomon 145. The lightness made sitting on the lift less tiring as well. The stiffness of the board was definitely something I had to adjust to & if I hit an icy area just wrong, I would catch an edge. Had a few frustrating falls, but after a few hours of getting to know my board I started to feel really comfortable. I felt that the stiffness gave me more speed, but also more control while making turns. On 5/9 I went back to Squaw Valley for my last day of the season. The morning conditions were slightly icy and I was again very pleased with my board. I easily shifted my bindings forward a little and again felt very confident in making my turns coming down the mountain. Going over bumpy areas seemed much smoother as well. I felt in total control. Iâm thrilled with my new purchase & canât wait for the next season to begin. I would recommend this board for someone whoâs past the beginner stage. I think I wouldâve been really frustrated if I learned on this board because itâs not very forgiving (due to the stiffness). But if youâre strong willed & not someone who gives up easily, this may be the only board youâll ever need.
