Thanks guys.

Well, my parents got me a set of glass blades for Christmas. They are SAB brand, 550 mm, and weigh 105 grams. I don't know much about them so any feed back would be appreciated. I just decided I want to learn autorations before much aerobatics. So that is my main issue now. I realize both my wood and glass blades will be fine for aerobatics.

I figure the glass blades will work better for autos, but they seem light(105 gr) Will they have sufficient inertia at this weight? Than again I don't want to damage good blades while learing autos(hopefully I won't damage ANY blades). How well will wood blades auto? I read that they will auto okay but how are they for learning on?
