Flatlines are notoriously harder on paint. It's the backspin being induced on the shot to allow it to "float" out there for longer range shots. The issue you're having is less the barrel and more the paint and weather. When I lived in the Poughkeepsie/Hyde Park area, we ALWAYS used polar ice for winter play up in the Mid Hudson Valley. The Valken Infinity is probably doing alright the the weather with a straight barrel because it's encountering less resistance and thus, has fewer chances to break. However, when you use that same thin-shelled paint in a flatline which is inducing backspin on the ball through physical interference, it causes that thin shell to come apart in the colder weather. Marballizer is the paint of choice for flatlines in regular weather (down to around 50*F) Polar Ice or another thicker shelled winter paint is what you need for anything below 50*F with the flatline.

I hope that helps!
