Ha, thanks Bryan
But yes, Red Balau shafts from Forrester Wood Shafts ( forresterwoodshafts.com ) I've never had a problem getting heavy spine Red Balau shafts from them. Good quality shafts too.
I've found Red Balau to be absolutely brilliant, super tough and heavy. The last arrows I made for Water Buffalo (130# I think) weighed just a fuzz under 1100 grains, and shot superbly from my 75lb Blackwidow longbow. With big sharp Grizzly broadheads up front, they penetrate extrodinary well. I cannot recommend them highly enough, and Kevin Forrester has been great to deal with.
Granted they are still wood, and I expect them to break when big critters fall on them, but in my experience Red Balau makes a fantastic wooden arrow for big things, like Water Buffalo
