Do you need to purchase topsy turvy pans if you have an Agbay or can you use the Agbay and get the same result as you would with the pans?

And for those who have topsy turvy pans (rather than cutting) does the thin side cook a lot quicker and do you cover with foil or what do you do?

You can use the agbay to make topys turvy layers. I have never done it but here is a youtube link that shows you how.... the info for topsy turvy starts about 4:28 min into the video. HTH

I use heat cores and bake even strips in my topsy turvy pans, and don't fill very deep, so they bake fine.  I  bake regular round layers to stack up with the topsy turvy layer on the top, to get the height I want.  After filling and refrigerating, I carve in the sides. When using the topsy turvy pans, I still carve in the sides, because the pans are a modest indentation, and I have regular rounds as the bottom layers which are not indented.  The advantage is that the top layer and the top edges are baked surfaces and sturdier.  It is nice, but the whole thing could easily be carved free hand as well.  the Agbay is not much help with a topsy turvy, (other than leveling the lower round layers as usual) because the top surface is angled and has to be done freehand. If you could put your cake on an angled surface and tilt it up, then you cut cut the top with an Agbay, but seems easier just to slice it off with a long serrated knife.  Especially because in this case  level is not the goal.  

AI've seen the topsy turvy pans, I've seen people tilt pans while they're baking in the oven. I never knew how helpful they'd be, I've really only sold a few and I have 2-3 pans for each size already. I've always just used a knife and carved with my cakes partially frozen (or very cold).

I've heard great things about the agbay but I haven't purchased one, I started with a cheap one that I hated then just switched to nicer knifes. I didn't check out the video, but normally they are meant for leveling straight across, I personally think it seems like a hassle to do it any other way but that's just my preference.

I watched it on the abgay site and they put a round cake on a binder covered with a non slip mat, what i meant by my question having never made topsy turvy cakes before, would it be as effective as using the tins, I am looking at buying a set but not sure if I need them or not.
