John.....I have fished for and caught many trout on both bluegill poppers and mid-size deer hair bugs. On bigger waters, and especially water where there is a mixed bag of trout and smallmouth, a smaller popper can be deadly for both. I have never purposefully fished for trout with a large-sized bass popper.....but deer hair bugs in the #6-10 range can be very effective.

Remember....a foam Cicada or Salmonfly pattern ain't much different than a bass bug.
