Pros: Flexible at pretty much all temps, sorry Alaska. Can be repaired if damaged. Ideal for shop use, or on the trail. Can be coiled into a relatively small package for trail use. Kinking the line will not damage it.|
Cons: Theft - it's a nice line and may sprout legs and walk away. Cost - typically a few dollars more than vinyl/plastic airlines, and twice the price of a Recoil airline.
Verdict: The few extra bucks to purchase a rubber line, instead of vinyl/plastic, is well worth the money. To put it simply, this line is frustration free.
