Ipe

I have Blonde Ipe

Dark verses Blonde  ??

How blonde is blonde(maple blonde, or light walnut)?
All the ipe I've ever seen has been dark brown. Apparently, the tree has sapwood, yellow/ greenish, grey, though I've never seen any mixed in with heartwood boards. Ipe is used mainly as decking and flooring, due to its hardness, and durability. A sapwood board in the mix would stand out badly, when laid out and probably wouldn't have the same resistance to rot, so I guess that's why you don't normally see it in a pack of Ipe at the timber merchants

I reckon sapwood would still make a pretty good bow though, its still dense as all heck.

Its light for ipe, but it doesn't look like sapwood to me. I reckon it will be good.

I was not very lucky with blond Ipe. I had more than one bow chrysaling away. I later discussed the topic with a more experienced bowyer telling me that it varies a lot. Blonde ipe generally is not so great, only the heavier boards maybe still ok. so you can be lucky or not. I would not stress the bow too much maybe. I personally will use my more pale boards for fencing now.   
density in general seems a good criteria for ipe, it goes along with quality (and also with color with the dark type).
I lately laminated a few warbows from different boards of dark ipe and noticed massive differences between the boards. the darker and heavier board produced a lot more drawweight at the same dimensions.

It's defiantly heavy and killed a new bandsaw blade in about 8" of trying to cut lams.

Bandsaw blades getting blunt. Yep, I remember doing that. A regular high carbon steel blade is no good for dense tropicals. You need a bi metal/high speed steel, or even a TCT saw blade if you have a large enough bandsaw.
