Great replies guys, very helpful indeed and has certainly answered a lot of questions I had. You're close with regard to size, it's a size 7.5 - Blade length 263mm. I did wonder why I didn't have a single 'flat' of the blade, I could rock the skate back and forward, but I do notice now that the mid-front side is *slightly* longer than the mid-back section. You mention that defensemen at your shop find a 20/40 profile good for manoeuvrability (255mm blade length). What's the equivalent profile you'd recommend for myself as a defensemen, 263mm blade length, or is 25/45 spot on? I love reading into the more technical side of skating, so this is all great to know :)
