+1 on not worrying about test casting as a beginner…you don’t know what you’re looking for in a rod until you’re a little further along in the learning process. I also think it’s generally good advice to not spend a ton on your first rod/reel combo, especially considering you can get a pretty nice setup relatively inexpensively. There’s other expenses to think about too…waders, boots, flies, boxes, leaders, tippet, floatant…spend some of that extra money on those.
My recommendation is to get something middle of the road (med/fast action, 8-9’ ft, 4-5wt) for around $150-$200 for the whole set up, reel and line included. Focus on the quality of the rod more so than the reel…for 99% of the fish you catch in PA, you won’t be using the reel. Spending that much will get you something that’s decent quality, and will make a nice backup setup if/when you do decide to upgrade or specialize your lineup later. The med/fast action will allow you to develop your casting stoke and learn what type of rod actually suits you best. If you do learn that you prefer a more medium action, or a really fast action in the end, the med/fast will still be a serviceable compromise when needed as a backup.
