Share 'Best sidearm disc for a beginner?'

I've just been throwing for about a month now and I'm still learning how to throw sidearm consistently. About the only disc I throw sidearm is a 175g ESP Meteor. I can throw it about 150' and still get a little turnover, but it "feels" heavy in my hand and when I mis-throw, it wobbles noticably. Does anyone have a suggestion for better disc to learn with? Thanks, Tall Tom
