I'm looking for a combo for some backcountry trout fishing in the Smoky Mountain. Nothing too expensive. I'm looking at this for the moment: http://www.basspro.com/White-River-Fly-Shop-Fly-/-Spin-Rod-and-Reel-Combo/product/44266/-949449

It been a while since I've used a fly rod, and wouldn't mind using a spinning if anyone know a spinning rod that can break down to several piece to put into a case that can I strap to mine backpack please point me into that direction.

Not a combo, but I recommend the Bass Pro Shops Browning Safari spinning rods.  They're $99.

See:

Good quality rods.

I don't do back-packing, but I use travel rods when I travel.  I prefer a 3-piece because of the backbone and strength.   I fish in places like the Volga River in Russia where I need heavier tackle, but for back-country trout, a 4-piece would probably suffice.

Then buy a moderately priced reel and you're good to go for around $150.

If Bass Pro is no go for you, you might consider Cabela's Tourney Trail rods, the Travel Spin at $69.  All are three piece rods. Cabela's also has their XML travel rods, 4-piece, at $149; or the Fish Eagle II at $89.

You could also put a "wanted" ad on several websites.  I found a great deal on some Castaway baitcasting travel rods that way.

Hope this helps.
