one is the 25 hard anodised - will only ever use solo but I had the idea that I needed the bigger size for pasta.
The other is the smaller 27 (damn that scandinavian logic) plain ally which I prefer.
I have bought 1 or 2 duossal bits since - damn again that upselling outdoor shop stuff.
In general I prefer stuff that isn't trying to be non-stick.
I also have this but have never used.

Cool. I have a 25 aluminium.
Always wondered if it would be worth getting a 27 too but so used to the larger size of the 25.
Love the idea of the mini (28) too for a little lightweight day ride lunch!
