I am happy with the sram yaw fd. no problems so far, and haven't had to readjust it since installing it last year. No need to worry about trim. I was worried that setting my high limit screw below the high trim of my Shimano trigger shifter so that both high index and high trim are at exactly the same physical position would put too much tension on the cable, but it doesn't seem to be a problem so far. I only had to widen the outside cage plate as described previously or on my other thread, by pulling the front of the cage until the unscrewed tail became around 3mm wider and then inserting a few washers before reattaching the screw at the tail.
