Golf balls in the winter

I wonder what the effect of 40-50 deg temp has on golf balls in terms of carry distance?  I have heard 5-10% loss but am unsure. 

As a medium swinger (95 mph, 135 ball speed, 235 carry) I wonder if anyone has any advice on what ball I should consider playing in these temps? I normally fluctuate between the ProV1 and NXT Tour during 70-90 deg temps.  Thanks, Tim
