I'm thinking about getting this and putting it on this rod:

I'm mainly fishing for trout, which are about 7 inches long at maximum. Would putting a 4 lb. test on the reel be fine?

If this isn't a good combo, could anyone give me an affordable combination? (Can be a combo too, just going to change line.)

Thanks.
