Treble Vs. Single Hook

I was doing fairly well getting trout to hit a 1/8 oz Kastmaster spoon. I
lost quite a few fish while reeling them in. On the ones that I did land,
the treble hook seemed to really tear up their mouth. I am considering
removing the treble hook and placing a smaller Siwash type hook in its
place. If this works, will exchange all the treble hooks on my spoons for
single hooks. Has any body experienced treble hooks tearing up the fish's
mouth? Any experience in trading hooks?

Thanks,
Rick
