Which size should I pick? (35" bass)
What you need to do is send an email to Jason at Bassstringonline and tell him what your bass is and he will send you a list of strings that will fit, including all the details on windings, etc. That's what I did a while back and Jason told me exactly what strings would fit my Peavey Cirrus.
Peavey USA Cirrus 5, Peavey USA Cirrus 4 Fretless, Gibson Les Paul Standard Bass, Genz Benz Streamliner 900 & Shuttle 9.0, Schroeder BMF 1215, Baritone & Tenor Sax (Yanagisawa B992 & T992)
