I like the B on my 33" just fine and hardly noticed a difference between it and a 35" bass. It's all in our heads IMO.
I'll entertain any notion...
But, here's my story: before I ever knew anything about scale length (heck I didn't even know what scale any basses where), I played a Rick at a music store back in '89. I knew that I preferred my Peavey Foundation's 34" E and A, but really thought the Rick's D and G sounded awesome. Ricks are what 33.25". Then flash ahead many years... I picked up a Peavey Cirrus 4 string at, coincidentally, the same store. I noticed immediately that the E sounded better than any E I'd ever played, so much so that I got on the internet when I got home to research what the deal w/ these basses was. I found out that Cirrus basses are 35" scale. I sold my Ibanez 34" 6er and got a Cirrus 6er... much clearer and more musical B string and improved E also. My eyes were opened and I started educating myself about scale length. Since then I've owned 2 Dingwall Afterburners: a 5 and a 6er. The B is 37", E 36.25", A 35.5", D 34.75", G 34", and the C is 33.25". Basically Dingwalls are built like a piano, and noone ever argues THAT design concept, LOL.
I couldn't adjust to the bridge slant of the Dingwalls

(I always play near the bridge), and decided that FOR ME 35" basses were the best compromise.
NOW, all that being said.... does it really matter? As bassist, do we really need piano-like clarity from our B and E strings? Probably not, but I prefer it

.
So, I'm glad to see some builders using 34.5" scale length. I'm sure that for some bassist, 34.5 will be pure perfection.
