Steve,
Great job and welcome back to wood arrows (I just came back after a 7 year sabatical this fall). I'm partial to the middle combination with the splice. I've always used three fletch and often would use one white cock feather and two graybarred turkey feathers with a 1 inch white splice on the back and it would be easy to follow flight with. For my last Michigan bear I used yellow and orange fletching and yellow cap. That shows up nicely right before zipping through a critter. I used to use Bohning years ago too, but everything is stain and dye now. I'm partial to yellow caps when I use them, but many times it's just fletch with a stained shaft.
So what's going on the business end of those bad boys for bears???
