Good Lord, Lad, can't you punctuate your posts? I get vertigo trying to read anything you post. You offend me, sir, by not considering those who may try to read what your stubby little fingers are jabbing out on your iPhone.
Nonetheless, let me make an attempt at answering what I believe might have been a question buried in that word jumble.
It's not just line weight, it's also the action of the rod, the technique you want to learn, the season you want to fish, the type of flies you need to use, the type of drag you want for the reel, the line capacity of the reel...
And I'm not even trying to make it sound complicated. You'll have more fun if everything works with everything else and if it suits the type of fly-fishing you hope, someday, in the distant future, to do. That means you have to consider all of those separate parts to assemble a useful tool.
If you're new to the sport, take the smart route: put down your iPhone, and visit a fly shop in your area and ask questions. Then come back here and ask for opinions about the answers you received. There's no better way to learn about the options than to go out and actually handle the gear.
Be more patient about learning about fly-fishing than you are when learning to type. You're at least a year away from being proficient enough to worry about name brands and top-shelf rods and reels, and if you're as lackadaisical about learning to fly fish as you are about learning grammar and punctuation, it may be more like 5 years. Probably 10...
Good luck.
