I think it's the Rabicano. Some of my rabi kids have grey streaks in their tails. Of course I can't find any now...but I swear some of them do!

I actually think there are two things going on here. The fact that the whole top third or so of his tail is a shade lighter is because of the dun. I've noticed some dun horses have this effect. Here are some examples:

You can see some of the horses in this list (especially darker horses) have this effect.

Meanwhile, I believe the whitening of the base and underside of this horse's tail is due to very pronounced rabicano:

To my eye, your horse doesn't show very much rabicano in his tail (maybe a teeny bit at the very top), but those white stripes/flecks are definitely rabicano.

That's awesome. Thanks so much for the info guys! Very much appreciated.
