Query: Works, but...

I have had trouble getting orange sponge cakes to release on the bottom. They cook perfectly, taste good, but I finally had to grease around the tube-base and around the outer edge of the bottom (definitely doesn't work if your grease the entire bottom... the cake collapses). I tried switching toChicago Metallic Professional 2-Piece Angel Food Cake Pan with Feetthinking that I could cut the bottom out after separating the tube/bottom from the sides... but that pan definitely doesn't work, IMHO.
