I just upgraded from the ice fly to the piano. They are stiffer, but it still only took me 30 minutes to initially break in. I broke down my ice fly within a year and a half. I have all of my doubles still at 38 and noticed they were breaking down when consistency started going out the window. Within 2 days the Piano felt perfect. They are stiffer but that's no issue - I used to be a triple bond harlick girl. I love the added stiffness... I got the narrower B width since I am actually an A/AA and don't feel like I'm wiggling at all - they feel so much more secure, but adapting to them was nothing since they still feel like the ice fly overall.
