I've never seen any of them come with a fly line that was worth a flip. For that matter, I've never been a fan of the Orvis lines either.
I agree that combos for beginners almost always have the cheapest fly line and often times a trashy reel as well.
I started with a beginner combo from Fishing Tackle Unlimited. Great rod. Terrible line.
FYI - since 2013 Orvis has owned Scientific Anglers and the current Orvis lines are made by Scientific Anglers.
I just bought my first Orvis line and it is excellent
a Lamson Lightspeed 2 with a St. Croix Legend Ultra 9ft 4pc in a 5wt with case and line $200
You just found an incredible deal.
Both reel and rod are made in USA should serve you well for a lifetime.
