What weight bait for Rainbow Trout?

If you can change your lures hooks I would do that first. A ten incher would require a #8-10 hook I would use single hooks since you get good . If the river is long you can use 1/16 or 1/32 sizes but it will not go far unless you put a couple of split shots or a 1/8-1/6 sinker on it. Or you can use a bigger size such as a 1/4 or 1/6 and change its hooks to a smaller size I usually do that first. I suggest Southbend rooster tails, spinners, and spoons. They work well, you can change the hooks, and they are inexpensive. If you use worms or grubs use wax worms or 3-4 inch earthworms. I would suggest bringing salmon eggs or marshmellows with you because they dont slip off the hook as easily as the other baits including dough bait.Remember the main thing is to fish in structures. Look for deep pools , undercuts, rocks, and slower water.
