Couple questions about your gemming. Obviously spell penetration is for explosive shot, but have you really noticed a big difference when you socket/enchant it? Also, why crit gems instead of agility with our talented scaling?
do you find it to be that much more of an advantage to have 3/3 Sniper Training or 3/3 Surefooted?
Have you come across situations where that change made a difference?
Avatar, why do u have a point in Go For the Throat? seems useless for your build, could have used the point in Improved stings, this way you would scale the damage loss from your glyph of wyvern sting ;)
