I see a lot of questions passing by about the ideal arrow weight. I think there ain't no such thing. It depends on the bow, the shooter and if you are hunting or target shooting.
Anyway, I am between the 9 - 10 GPP, depending of the bow and type of arrow.
In the past I made a poll about this and LOTS of Tradganges gave their input!

i'm with you on this, depends on what the bow likes.
depends on the terrain & situation.
This subject invokes a saga which again will be broached time and time again. Many may have repetitively travelled the route until they have become bored and/or irritated. Since subjects such as these have no absolute answer, we will continue to see a wide variety of attempts.
Choosing to again join the circular journey is but our choice. Most times I restrain myself and choose not to ride as the path is already crowded.
