I have used them many years ago and, like you state, they work fine. I no longer use them because I found that they do cause the fly line coating to crack where the pointed end of the eyelet ends inside the fly line. They also make a 1/2" to 3/4", depending on the length of the eyelet, place in the fly line that will not "give" or be able to flex and this "flat" spot will hang up some times in the fly rod tip. Another thing I noticed was the barbs would eventually protrude through the coating of the fly line just enough to nick the eyelets and rod finish. They will also rust. They work just fine for what they were intended for and I guess if you are happy with them and are having no problems with them, you need to just continue using them. Life is too short to make changes just so you can be like all others.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
