The coils will give all the flex, but will be more predictable. They'll have what I call useable flex. I have a missing link, and it's not great. In technical sections (like a boulder field) it works well, but when climbing, descending, or sidehilling they can unload which gets a little scary. I also think the missing link setup introduces more slop into the suspension for general on road use. I would go yj springs without missing link, or if you feel like spending some time and money, the coils will rock.
