I recently bought the larger Dirty Bird Scuttle. I have a GTP G5 and I'm not that impressed with heat retention. Also, the opening is only around 3 1/2 inches across, so it's a bit tight. The DB is larger 4 1/2. As far as heat retention, I don't suppose it'll be much better.

One thing I've been thinking about is the the G5 has a cork which is a great feature. Even though the heat retention sux, I imagine it would be worse with a hole allowing heat to escape. Since most scuttles I see remain open, Has anyone come up with a way to plug it up? I don't think my cork from the G5 will fit.

I'm thinking of using a piece of sponge or something to help hold in the heat in, or is it really not a problem....? Any Thoughts...?
