I'm considering a few Falk pieces and have engaged in this internal debate. I prefer the traditional CI aesthetic but do prefer the ability to stay cool that Stainless provides.
Also, it appears to me that the stainless handles have better ergonomics. The lack of loft of their stainless is appealing to me for things such as tossing the pan and moving it to the oven when needed. I'm guessing the higher angle of the CI allows it to stay somewhat cooler than if it were low.
I've read some mention that Falk's handles are more ideal for small hands. Did this refer to the cast iron, stainless, or both?
Sarah was gracious enough to send me a photo of her Mauviel and Falk stainless handles side-by-side and the Falk was much thicker, which I liked.
