I have the Ethos and the Silver FeatherWeight. I prefer the featherweight because of the rasied rib. It definitely fits site line better. The Ethos is a great option but the Silver Featherweight is a better fit for me.
I have to use non toxic where I do most of my hunting and I have had good performance from Blackcloud #3 in 1/4 ounce. I used to go with a cheaper steel in the same shot and had too many runners. Since switching to Blackcloud, more times than not they are laying where they landed.
