If it was me, I would use cocobolo..or cocobolo. Just sayin. but bubinga or bloodwood would be ok.
Go with something in reddish range unless you wan't it to look like a patchwork quilt. Of course you cant use the cedar as it won't make reliable riser wood.
Too often, guys combine to many different woods and or colors and instead of adding, it takes away from the bow, it looks like wood bin clean up.
Just my .02
