X2 on the P3 controller. I love it. Had a cheaper voyager and had to keep adjusting it depending on hwy or slow roads. The P3 is set and forget, no more locking of wheels when in a town after being on hwy. just make sure you shop around as I am sure there are more than just the P3 that are good. And make sure you check eBay.
