Quick tally of most common answers to OP's question - there are about 5 people who have since come around to the teebird, and the most common with about 6 is the leopard. Bit of a surprise - seems like the most beginner friendly driver in existence.
The Innova Starter Pack has the DX Leopard in them, but it's usually 150g or so. I'd imagine that as players get better, that disc will start getting flippier for them and they'll end up looking elswhere. Then some time later they come back to it (or the Leo3) and realize how good things were all along..
