Being that I just cannot make myself shoot very far anymore since the deer can move vs the slow speed of the arrow, I have not used one for years.
Especially on my recurves.
For pure accuracy yes, I do remember those years when I shot extremely well, out to longer distances and thought that anyone should be able to do the best and make shots at 50 yards with a bow very easily. And I have.
But I now know better and owe more to my deer personally, as such no need for a stabilizer.
When I did run hunting ones, fronts were the only ones, and appx 8-12 inches.. I had a couple of heavier shorter that I did not think did much or enough to be using.
I liked the twin v rear facing ones for target bows. But not hunting.
