Yup, I'm definitely still a fan. I'm not sure if there are any big changes between the 3Ws and the new 4Ws, but the 3Ws have been in all conditions I use them in at this point, and I have been really happy with them.
Not really cons, but with the extra weight over the old Hankooks (also load E), after leaving the MPG monitor running without reset, they have averaged out to 1MPG less than the Hankooks. Pretty expected, and for me, no big deal. I do still wish I could have gotten mine in a load range C, which Wildpeak makes, but not in any size that goes on my 4Runner without buying new wheels. Still, between an E and P tires on anything going offroad, I'll always take the tougher and heavier E.
