Will 4lb Fireline spook trout?

I'm sorry that this is not a fly fishing question, but it is a trout
question. Will 4lb smoke colored Fireline scare trout? I normally fish
for smallmouth and will be on a trout stream in a few weeks. The
Fireline is much thinner than 4 lb mono or fluoro but not clear. Plus
it casts farther. I'm wondering if the casting distance, plus the
"thinness" will make up for the lack of "clearness".

Thanks!

Chuck.
