I mean it really depends on what you are looking for. The flex force will take the sting out of a fall, but you will still feel it, where as the skeletools will make u not feel anything, but will also look like you shiz in your pants. Just my opinion.
For me, I don't really care what I look like, so I went with skeletools. I rarely ride w/ anyone, and almost never someone better than me. One dude i go to the mountain with sometimes skis and he wears solid purple with lime green stripes on the pants... looks awesome when bombing a run though.
