Just had an interesting experience with this topic.
I have new Dean 35" fretless that I was looking to put set of TI Jazz Flats on. I did the noob thing of just looking all over for TI 35" flats without posting a question here or calling. Anyway, I couldn't find any TI 35" scale strings anywhere. So I did the "safe" thing and ordered a set of JF-365s. WRONG! I laid out the B string and the taper and windings at the end of the string started at the tuning post! I got a "deal" at MF for $59.95 so I got them on the phone. The first call resulted in a nice conversation that ended with "Sorry, strings are non-returnable items". I sat for a while and thought about the prospect of having a $60 set of useless strings lying around. I called MF back and talked to product support. They wound up giving me a Return Authorization and an order for a set of JF-345s for $79. The weren't on sale
Anyway, to second the last post, I was told that JF-345s will fit a 35" scale that isn't strung through the body. We'll know for sure when they get here! I gotta get better at doing my homework!!
