Hi Walter,
it's great to jump from one board to the other that share the same shape, the only difference being the volume. I used to have the 75, 85, 95 from the 2010-2013 Freewave shape and it was great to find the same feeling when switching boards. Things got complicated when I replaced the FW 85 with the Classic 2017, the newer shape felt smaller and it almost overlapped with my FW75 2010. And even more when the FW95 2012 got replaced with the STB95 2018.
So, if you love your STB 85, maybe the STB 95 would be a good option, specially if you can get one at a good price. One thing for sure, the STB 95 meets you huge range criteria.
