My whole point was to present the op with all the info. It's his choice. I didn't run a dr on my setup because I saw no reason to. If he's considering going with an xp, he should at least know it's recommended by the people who make the cam. I agree if he goes with 105s, and sets his idle somewhere in the 700-800 range a dr is overkill, but I just wanted op to know its something to consider. Many members on this site have run it, many have not with the xp.
It says it specifically is needed for an xp, now we all know zzp is full of sh1t, but, it should be considered.
