I don't know that a Gazelle has the power threshold of a Teebird, so the distance capability might not be quite the same. But, straightness, oh yeah. That's one of the reason I loved my beat Gazelles, almost got a 265' ace dead bead from box to the basket, it dropped about an inch too much and banged the cage. Had 5 witnesses too, would have been a sweet ace. But, they are much easier to throw, and they do beat in to be more versatile than a beat Teebird. But, I'm not quite sure the distance capability is there, but they aren't shabby by any means. I'm sure a slight beat even mildly beat one could be pushed really close to a Teebird. If I had to choose one, I'd definitely choose the Gazelle over the Teebird.
I'm glad to see them back in production but it was just too late, I already got rid of all mine and moved to the TP Cyclone and I'm heavily invested in them. If I ever switched from the Cyclone I'd probably throw the TL since I'm already invested in it as well. But, it would be a hard toss up between the Gazelle and TL. I'd side more toward the Gazelle, especially if they gave me a Star Version as a slower beating alternative to the DX's.
SOLF for longer alternative/line shaping ability with a Star Gazelle for stable straights/windy line shaping and a two DX's for turn overs/normal shaping duties. The Gazelle being a direct replacement for my Cyclones current position. I could see myself throwing that. But, then again I dunno if I could ever get away from Cyclones now.
