My Force 4 is the nuts, I couldn't be happier with it. I tried a Speed too, and I personally prefer the look and feel of the 4 It's a little lighter, little smaller, and I just found it more comfortable. And for only an extra $150 I got a one of a kind color and milling pattern, and lifetime tech support from the best WDP techs in the US. I think the force is the best angel running.
