Streams that produced wild tiger trout

[wildtrout2]

For those who have caugh wild tiger trout, I'm curious what the population of that stream mostly consists of? Is it primarily a wild brown trout stream with some natives, or a mostly native brookie stream with some wild browns?
The stream I caught my one and only wild tiger on is roughly 98% natives, with very few wild browns. I actually fished it for a couple years (maybe 8 times) and only ever caught natives. Then, out of nowhere I caught my wild tiger. I had never seen, or caught any wild browns and wondered how this could be? After catching the tiger I went another couple years before catching my first wild brown. This was in 2009, and since then I've only caught a total of three browns on this stream.

Curious to hear what others have to say. I'd especially like to hear what FTA has to say (if he sees this thread) on the subject, since he's caught an amazing number of wild tigers.

I’ve found them in what was formerly a native brookie stream that is now listed as wild brown and brook. That tells you the browns moved in and are breeding and the brookies are fair game come spawning season. I would assume most any stream in PA that has wild brown and brook would fall into that category. Now you’ve just got to make 10,000 casts to catch one.
