I’m the original poster with a new forum username. This is my current motley collection of gloves:
not shown are a thin pair of Pearl Izumi for temps around 61F/16C. The alpine ski gloves on the left side of the pic are only used on the occasional 8am group ride in late December or January when its 32F / 0C at the ride start. They were about $15 at Costco, and only used on the bike a handful of times a year. The thinner Head gloves are great for cross country skiing, and cycling in temps 35F - 50F (2-10C), and were also about $15 at Costco.
Given the few times I use them during the winter, its hard finding motivation to buy a nice pair of cycling gloves for (mostly) training rides. I always wear padded summer gloves inside the long finger gloves.
