Sugar maple is one of my favorite bow woods, Im working on my 4th bow with the wood it has made the fastest bow I have ever made , but design is important as it can be compression weaker then some woods , but needs sharp tools to work, it can be prone to tear out , in stave form it doesn't seem to reflex as it dries as much as hickory or osage. Plus you can generally find nice strait grained wood ! Its often over looked bow wood but if worked with in its limits its great stuff !
