The Stingers would be an excellent choice, especialy with the lower KE level of your crossbow. The 100 grn heads may be a bit better in the accuracy dept as they are a little smaller. The problem with straight fletch and a short " arrow" are how stable they will be in flight. smaller heads will help with your accuracy. The slick tricks should also work well, and they are the broadhead that will shoot most like a field point, fixed blade that is. I don' t think you have enough KE for most mechanicals, maybe the Rocket nail driver, but it is kind of small.
