I'm going brook and rainbow trout fishing at a river and don't know where to start.  What type of line and what strength of line do i use?  Anything helps!

6 pound test would do

Take a rig with 4# on it, most times smaller is better. Good luck! Tom

on the rare occasion i fish for trout  the rod and reel is set up with 6 lb. P-LINE

( A US REEL 180 XL ON A 7' MED FLEX BERKLEY AMP ROD )

When stream fishing for brookies or other Trout, I will use 2 lb to 6 lb. monofiliment. The lighter line will catch more fish as it won't spook them as easily. When trolling with downriggers for Lake Trout  I will use 14 to 17 lb. line to give me better abrasion resistance  and strength as I am trolling some heavier tackle like christmas trees along lake bottoms; then if you add a 6 to 10 pound fish to the end of all that, I like to have a little extra beef between me and a Laker with a mouth full of razor sharp teeth. I don't mind losing a fish every now and then; but I hate to lose $10 to $25 worth of tackle too.

.

A real key here when trolling is your leaders and knots. Also checking those leaders for wear and tear often.

hello all,
for light spinning tackle, 4lb-6lb Vanish will do it, plenty of knot strength to handle most trout,
make sure the reel has a good drag.
for fly fishing, 4,5,6 wt WF/DT  with a 5x or 6x tapered knotless Mirage tippet {9ft.-12ft.}.

I use both of these and they can handle 6lb Apache trout as well as monster German Brown...

I prefer the flurocarbon to monofilament for its superior wet knot strength
and its invisible to fish
{and people} underwater...
forget braid if you are trying for educated trout...they will not take it very often.

good fishing

i use a 10 pound to 8 pound main line (trilene smooth casting) then a 6 pound leader line (maxmia ) a long leader thoe at lest 18" when i float fish remember if you aint producing fish change your shot pattern if your drifting

Anything that can be added? I know there's somebody out there just startin' out...

Since this question was asked...there are a few new lines on the market. I am using 12lb. Nanofil(the diameter of 6lb. mono) on my trout combo.
