Your last statement contradicts the first (at least here) so I'm not sure what the actual question is.
In general, I don't notice stickbow guys trying to shoot the lightest arrrows from the lightest bows. I may see some trends in people shooting lighter weight bows, but not at the limits that would make hunting unreasonable.
Of course, one persons "hunting weight limit" is not the same as anothers.
Also, "hunting weight arrows" has a fairly wide spectrum....type of game is one of the many things to think of when setting up an arrow.
