Bow Grip of Defense or Bow Grip of Shelter ?

Ok which grip do u think would be more beneficial?

Since Rangers already have a high elemental resistance does the +5 armor of the defense grip when used against elemental dmg really make a difference?

Or should i go with the +7 armor (vs physical) as it will only give me a +2 armor difference from the +5 defense grip but only for physical damage? (since i have high elemental res)

So my big dilema is should i go with +5 defense grip and have +5 extra for elemental and physical?

Or choose the shelter one and have no + extra armor vs elemental and have an extra +2 armor vs physical?

Thanks for the help in advance. I really appreciate the input.

the +2 armor will prolly only reduce like 2 damage at the most (i dont know the numbers), but id go with the +5 since it applys to both
