I used to switch between the 2 shock mount positions on my Mega Trail to adjust travel and HTA. But then I invested in an air shock with shorter stroke for days when I want to drop weight and travel so now I just about always use my coil shock in the 165 setting and swap out the shock for XCish days. Although I am still playing with both mounting positions with the air shock, dialing in which travel setting is best for different trails.
