I smiled when I read your post. I would have loved to have traded my 535 for your beautiful Sadowsky
I owned a maple/rosewood 435 with an ash body without a top and I still own a 535 wenge/wenge with a korina body and myrtle burl top. I talked with Mike Tobias about the selection of woods for the 535 and, at that time, he felt that the top made only a slight difference in tone and was mostly cosmetic. This was a while back and I note that he is making a lot of instruments with exotic tops now.
The main difference between by 435 and 535 was that the 435 had a more "traditional" tone while the 535 is extremely aggressive with a "growl" that the 435 didn't have. Personally I felt that 435 had somewhat less clarity but that depends on what you hear as clarity in a tone. What I mean by clarity is the ability to cut through in a band situation which some people interpret as uneveness.
It is worth bearing in mind that the Bartolini pickups are fantastic and the electronics are very flexible so you can really tweak the tone you want.
Even though my 535 has not turned out to be a perfect match for me, it is a very wonderful bass. I am sure you will be happy whatever combination of woods you choose.
Best wishes
