Its a beautiful wood. You can check the link that SS posted for the Sass bow I made.
'Normal' Sass bows would be of the medium weight english long bow design, like the Thompson brothers would have made. Sass tends to be weak in tension so one solution is to give it a round belly to transfer the stress over to the belly so it just take some set instead of breaking
I went with more of a "meare heath" design. If you do that, I'd advise you keep it long (say 68") and wide (2 1/4") most of its length.
If made/tillered well, Sass bows will take almost no set and are very light in the hand.
If you back it with hickory- as I would suggest with a board bow- you can be a little more daring with design.
I'd say go for it and take pictures of your results.
