One of my 'secrets' is replacing my trebles with the 'new' colored hooks (maily octo). Especially in the low clear water, the dull grey and green seem to help in this situation. The reds and hot pinks are also a good way to spice up a lure. Sometimes I'll even att a small bit of yarn wich I add scent to. - oops - there's 2 'secrets' I think it may also help a little when the fish try to spit the hook quickly (yarn catches in the teeth...). Between the added color, scent, and possible teeth catching, yarn seems to be a good move. Just don't put on too much on a spoon (unless you are purposely trying to slow down the action...).

I think this works will when the fish have been more pressured and get gun shy around anything that is too 'shiny'.

Only problem I have with the octo vs the siwash is that I have to either bend the hook or add a split ring to the octo - most siwash have an open eye for quickly slipping on and clamping to your spinner\spoon.

Since most of the waters I fish (trout, salmon, steelhead) require single\barbless (like the snoqualmie and its forks), I tend to do this as soon as I bring the spinners\spoons home.
