Is there a difference between a 1st run and the other runs of the elite z-flick?

Yes, from what I have noticed, the 1st runs are not as overstable.

I have noticed this as well, however the Flick is so stable anyways that it is hard to notice, you definitely have to go to a field to see a difference.

Wow, the first run I threw is about as overstable as any disc I've thrown. really low profile too.

My friend actually got his first ace (amazing shot) with it yesterday and I was looking on ebay and they didnt have any first runs.
