So after driving around with both the 3.813 and 3.826, I decided that there is no significant difference (if you want to be really specific, the 3.813 a very very slight advantage in sensitivity but also more ghosting).
The 3.826 is on ebay as we speak. I am considering putting the 3.813 up for sale as well and getting a refurb from VR. Do you think I would see better results from that? At the very least I would have a warranty and be able to get free tuneups. And the cost ends up being nothing (I may even make money) the way V1's sell on ebay.
