That's it! Funny, I looked on that site and didn't see it. Good find. We were using sink tips with it but I recall it being weighted. Maybe try both? I think that might be the key--having a variety of things to try if/when one things stops working. You might find that you're on a bunch of fish, hook 15 and then they just stop biting. That's when you want to have some other things to try. Folks have suggested some good ideas. I remember one time where what I described happened, and I put on a copper & gold kreelex and started hooking up again.Something like this but weighted? https://www.alaskaflyfishinggoods.c...almon-flies/382-coho-kryptonite-chartreuse-2/
You may find fish in slack water that require a more subtle, stealthy approach at times.
