Out of sheer curiosity...
I had an opportunity to try out a several 35' scale basses a while ago, and noticed that some of those necks feel really huge and with some necks you don't feel any kind of differences if compared to "regular" 34' scale.
For example: one of the basses was Lakland Skyline 55-01. It felt just like a "normal" 34" neck. It was fretless, and I didn't even have any kind of intonation problems, which I assumed to struggle with since I've played the 34" basses exclusively. Lakland's neck felt very easy and familiar.
On the other hand MTD bass's neck felt quite massive. I could really feel the 1" difference, the string response and resonance was somehow stiffer. The neck was also feeling longer.
So my question is that what kind of constructional differences can make the 35" scale feel longer or shorter? Hopefully my question makes sense to you, since I'm not a native speaker!
