RE: FINGERS OR RELEASE?
Most folks today are typically better served using a release as opposed to fingers simply from a time perspective. They don't necessarily have the time or motivation to learn to shoot fingers anywhere near as consistantly as a mechanical release.
As for points, non-expandable, I am rather fond of the new small replacement blade heads on the market. The NAP Nitron, Rocket Ultimate Steel or Slick Trick 100s would get my vote.
