At a glance
The Karlsson is stiffer (85 flex) with a TC2 Mod curve, while the Bertuzzi is slightly more flexible (90 flex) with a T28 curve. The Bertuzzi is $30 cheaper and uses a curve that gives you more blade versatility if you like a mid-range pattern, but the Karlsson gives you Karlsson's actual game-tested setup if that matters to you.
