Curt I 2nd the Muzzy spincast reel with 150# line, that is what I use and I know I get better penetration on deeper, bigger fish with that lighter line. I always bend my barbs in close to the body just leave them wide enough to pivot around the shaft and they do penetrate much better and leave a smaller hole as well.
Those little black river pts are small,but the barbs are very thin and will break very easily and do not hold fish well at all, we use to sell them as our cheapest bowfishing arrow, but they just broke too easily to continue to offer them.
I just wish I could post some pics of the original Muzzy fish head prior to the wire barb version, you would be suprised what it looks like!!!
