This ones hard to say, Jasper is the best fighter in the Cullen clan and has the most experience in dealing with newborn vampires who are in twilight fiction physically more powerful for their first year. So jasper knows how to fight a stronger opponent yes... But only due to experience. Age does have nothing to do with it, newborns are inexperienced fighters even if they are immensly powerful physically. Felix is over 1000 years ago and his special power is stated that he is stronger and faster than your average vampire as he is always several steps ahead and he does dominate Edward but its explicitly stated that Jasper would do the same if Edward couldn't read his mind and on top of that they are only training! Not actually trying to kill each other. I think 1 vs 1 Jasper Vs Felix would come down to what ever the reason they were fighting. Say Jasper was was fighting for Alice his chance would be greater. Felix has been forced to be loyal to the Volturri so this isn't a strong enough reason to strive to win more ( my personal opinion ) Jasper never lost a fight don't think he'd lose to Felix thats for sure.
