This is a bit that I missed previously, but a point worth making - this is where a pricier rod shines. You're going to notice a world of difference between your Ugly Stik pricepoint rods, and a more expensive rod. Of course, I understand that you may not want to drop $, but if you plan to fish it a lot, it may be worth the upgrade.
A few considerations that I made... (I did extensive research before buying)
7'+ was definitely at the top of my list. I wanted to be able to cast this thing a mile, and with precision. Snakeheads spook really easy on some days. There have been times when we could walk up and spit on them, and others where you can't get within 30 yards, before you see torpedo wake on the shoreline.
1-piece. I hate multi-piece rods.
Lightweight. You can actually create some pretty interesting problems with your back, slicing a rod through air all day long. (also a very good reason to become a switch-handed caster) So I'm with you on that one. The rod(s) that I ended up with are feather light. Not forward heavy. Or heavy in any way at all, really.
Micro-guides. Braid is a great thing, but it comes at a price. Between a larger braid size (because it costs the same to spool 10lb as it does 65lb at my local shop) and micro-guides, I've gotten the wind knot issue completely negated. It's literally a zero issue for me. I feared that it would affect casting performance, but I have zero complaints.
Light weight. As I mentioned, we fish over 8 hours at a pop. Gotta be comfortable. This is also the reason that I chose baitcaster over spinning. (the balance, and CG of the setup) And a cheaper rod with a lighter weight, is a poor choice. They skimped somewhere to bring you a compromise. If you don't fish much, or don't mind disposable gear, it's OK. As with everything, buyer beware.
For the reel...
I chose one with a lot of drag. 25lb, to be exact. Now, I've got ocean-going reels that have this amount of drag or less. So you don't need it. But any reel that can handle the drag, has components that can stand up to it. Or something d**n close. You will probably never catch a snakehead that can pull that much drag. But overkill often gives a comfort factor in all the right places.
Gear ratio. I chose a high gear ratio - 8.1:1. Simply because when a good bite is on, there's no such thing as too fast for hand-cranked speeds. Snakehead are the barracuda of the freshwater fish, for me. I'd rather have the extra speed and not need it, than have to spin faster on a slower reel, when I do.
When I finally made my purchase, I tried to find the most economical gear that met all of my requirements. I spend a good chunk, but it would have been easier to spend 2-3 more, without even blinking. I figured I'd chime back in, because you definitely listed some specifics with regard to your fishing style and/or physical preferences.
