Kyle was a decent GL - despite his stupid mask - prior to Winick. But Winick - with his imagination and creativity - made him great.
And then came his GA run. Now, I suspect history will be kinder to it and I didn't find it as bad as some, but he followed it up with GA and Black Canary which was downright fucking horrible. Especially what he did to Connor.
That said I'd recommend that whole GL run that began in the 1990s. I think it ran for about 180 issues and also had some great stories by Gerard Jones and Ron Marz.
