I agree the hand and thumb warmers are below standard when compared to years past. I have the updated bars on my 06 Attak. I solved the problem by getting a pair of gloves that have little insulation on the palms, but plenty on the top. I think that getting heavy insulated gloves with allot on the palm won't let what little heat they have reach your hand. The mid windshied helps keep more of the air away from you hands than stock, and aids in keeping my whole hand warmer. I know this is going arould the problem but it's what works for me.
