I tried using a 4 season JRB UQ but found it difficult to eliminate the cold spots. It could very well be me that is the issue but I need a more "fool proof" UQ for my Ridgerunner. It has to be a full length winter / 4 season UQ as the title states because Im a cold sleeper and I do get out in the winter here in NY every so often.

Thanks,
Sprout
