Note: Monkey Grip does NOT extend the range beyond normal; reach weapons specifically say that the double the range of the creature using it. A bigger Spike Chain doesn't actually do anything.
I never said it extends the reach of the weapon. I said it does help with the damage output which it does do

Strongarm bracers give you that larger weapon size without losing a feat
I do not know this item but it looks like a excellent choice. Book please?
