I just got some new Carbon Fury Arrows (Cheapos) that are 60#-75#. Do I need 100 or 125 grain field points?

It all depends on the length of the arrow, the make up of components, and your poundage on your bow. If the arrow spines out with the heavier tip though, I would go heavier. But you need a little more info.

64# draw weight. 27 3/4 " arrow. My last batch offield points were included, so I didn't ask what the grain was, but I know for a fact it is 100 or 125.

Whats your broadhead weight? Your field points should be the same.

I've only owned a bow for 3 weeks now, so I haven't bought broadheads or anything like that yet. I was just wondering because I grabbed 100's today, and for some reason they look like a different size than the ones that were on my arrows. It could be the wear from 100's of shots.
