I play a Jay Turser JTB-134 short-scale hollowbody with a "trapeze" style tailpiece like the one below. I tried short scale Rotosound tapewound strings but they were a bit too short and the flexible wrapped part of the string sat in the nut. It may be unrelated but I experienced intonation problems (wavering pitches on sustained notes, for example) and some notes with no bottom on the E string while I used these. I changed to medium scale La Bella flats but they're too long and a bit of the string gets wrapped around the post. I read that this leaves the string prone to breakage. Which type of strings should I try next? I do not use roundwounds. Thank you for your help and advice.
