One of the more important indicators of a woods strenght is it's specific gravity...(SG)...but this is not all to consider. Take for instance the birch you mentioned; it has the same SG as ash. they both weigh about 42 lbs/cu ft. Ash is used for tool handles, flooring and even baseball bats. Birch has little value in the woodworking industry except in painted and stained furniture. It is far more brittle than ash and is more readily attacked by fungi. So in this case, if you have the option, use the ash. That's not to say birch wont work.It says: for the same weight penalty, ash is the choice here. What other options are there? Honduran Mahogany...................34lbs/cu.ft Fir (douglas).................................33 " Sitka spruce..................................28 " Canadian spruce............................28 " Pines,..Vary from 22 to 33 lbs/cu.ft, most US pines closer to 33, while the canadian pines will vary greatly from the 22 to the 33. You can see that the biggest bang for your buck is the spruce, with fir running second.
