I haven't played a 35 inch scale 5 string, is there much of a difference from a 34
IMO, yes, and it is worth it. I used to hate stretching to play 35" scale, but for a long time my primary bass was a 35" 5 string.
I bought a 34" EBMM Sterling 5 (not the cheap brand) thinking I could "upgrade" back to a 34" 5 string, but I felt that the B string was a soft & floppy - and I thought the E string was soft and floppy as well. I traded it for another 35" 5 string and never looked back.
(I bought a 35" scale 4 string recently and love it as well... I used to hate 35" scale!)
Obviously 35" is my personal preference and lots of people like 34", but to answer your question, yes, I think there is a difference.
