I had a BBI break on me at a pin knot, that I didn't see... check. double check. and then if you rip cut a section of a larger board check the fresh cut side too. (looking at it under bright and direct sunlight helped me scour the rest of the board and realize it was useless...
There are several guys who also sell clean IPE on here too if you cannot find any.
Best of luck.
