Crankshaft for Polini 102ccm on Vespa Pk 50 XL?

Hello. I’m rebuilding my pk 50 xl. I decided to set up Polini 102ccm. But what crank to choose for best performance?

Now I’ve already bought: Polini 102ccm kit, 19/19 carb, 4-plate clutch, 3.00 gear and all bearings and seals. So, all i need is new crank! Please help me to choose.

Get a Malossi Crank but even better if they sell polini evo 2 cranks for your bike here get that instead!
