from the poly light series? i think thats it, what do you think performance would be like in a 5700mm 4 tec? i have a chance to get one reletively cheap let me know thanks!
That should be plenty for the 4tec, as long as your gearing doesn't push too hard. I would personally go with the 20C series, but if you are getting it on the cheap then it will work pretty well.
