As for the pin's ,Yes they're definately brighter ,but I've not been able to get out as Gibblet say's ,since we've still got 4 feet of snow on the ground .
I'm a little concerned about the durability thing as well ,but Authur P say's he has a quick fix for covering the extended fibre's ,so as they don't get hung up on branch's .but I'm still waiting to see what he has come up with .
Ausie Guy is a master at this craft ,and is the one who gave me the idea in the first place. I was complaining about losing my pin's well before last light while hunting ,and he gladly helped me out with this matter.So as soon as we get some relief with the snow I'll know for sure .
Don't worry about ruining your sight ,because fibre's are real cheap ,and if you don't like it ,you can alway's change it back .
