The one problem I can see with the Bradley bisquettes (other than price), is their availability. After checking with Amazon, they average .44 a piece, buying a 60 pack. I can get chucks for much less.
If you don't buy them online, there are very few places to buy them locally (at least in the New England states). So, if you run out, you have to wait to replenish your supply online and wait for delivery, whereas, if I run out of chips, chunks or logs, they are available at many outlets anywhere.
