Pirelli Scorpion Verde or Zero PNCS for RRS?

[lime1]

Need to change the rear tyres on my 65 plate RRS HSE Dynamic. Pirelli Scorpion Verdi are I believe the LR OEM. I see however that Pirelli also do a Scorpion Zero PNCS (Pirelli Noise Cancelling System). Both all weather tyres. The Zeros seem to suggest better fuel economy, wet handling and less noise than the Verdi looking at EU rating. Anyone used the Zeros or have any comments on them compared to Verdi?
