Winter tires for New England

Hi,

Looking for some recommendations on winter tires. I was thinking 80/20. I use D606's but they are not very good on wet roads. Given that I will do far less trail riding during the winter, I've decided to invest in tires that will be reliable in rapidly changing (Boston) weather conditions. Then I will put the D606's back on in the spring.

Currently looking at Heidenau but I am open to any suggestions.

thanks!
