The Novara stratos 2 looks nice. Reading the few reviews on REI confirmed my thought that it's a good jacket mainly for rainy areas and you should definitively see some improvements over your current jacket. I think it's a little heavy duty though and that improvements in terms of breathability could be bigger with other solutions especially due to the lack of pit zips on the back but maybe this one will answer your needs that's what matter anyway. I will be interested to know the results of your test tomorrow.
