You really can't wrong with either. It really depends on your tastes as far as being able to take the sight off easily or adjust it in or out to fit your peep. I personally went for the simpler Hunter model.
As for the wrap kit. I think I might buy one eventually, but have not had a single issue with the brightness of my pins. You might want to buy it without the wrap kit and see if they're bright enough for you. If not, you can always buy the wrap kit seperately later.
