Hi all I am a total new comer to fly fishing ect..

[EdD]

Welcome aboard.

Since even very small 'gills will swallow fairly large flies, I seldom fish anything small than size 12 flies for them. Also, make sure you have a pair of forceps, Ketchum Release tool, or something similar to help you remove the hooks without injuring the fish you wish to return.

If you are new to fly casting, I would start out with at least a 6-weight rod and line because it will be easier to cast. Remember that the rod casts the line and the line casts the fly. With spinning, baitcasting, and spincasting gear, it is the weight of the terminal tackle which drags the line out behind it. The heavier 6-wt line tends to be easier to cast than the lighter equipment you might favor when you have more experience.


Regards,
Ed

I've never used a fly rod in warm water, but can possibly help interpret.

The rod "weight" generally refers to how much it bends in response to a pull from the end of the line - be that from a fish or the weight of the fly as you cast it. Bigger fish require higher weight rods.
