Where is the best place to use FM brawling gloves in runsecape

Edgeville-Wild wall.
Simply wear them, get your logs and then start burning them.
Bank in Edgeville, very easy.
If you want to be risky, level 55 wild at the mage bank. You would need a sharp weapon for this. This is NOT recommended as this would likely be just as long.

If you want to stay as safe as possible simply make them in runescape, not the wild as you will receive the same xp, just not as fast, and it would cost more.
