Last year I moved the Fox Stepcast from my mtb over to my Cutthroat for a few rides. It was nice, and it made things a fair bit more comfortable. I didn't really notice much change in efficiency (when climbing etc.). One thing it didn't improve much - washboard. We get a lot of it around here, and I was hoping it would really help. Not really. Just don't think it can cycle through the suspension fast enough. I've heard different things about the Lauf - some say it really improves washboard, others not at all.
Only problem is with A to C measurements. The cutthroat is designed for a mtb suspension fork. So even if you go Lauf, you can’t go withe the gravel version.
