The LaBella LTFs seem nicely balanced to me. But oddly, their website says the tension is:
Total Tension in Lbs: 134.90 (1st 36.2, 2nd 34, 3rd 30.5, 4th 34.2)
Which shows the A string as being significantly out of balance. The gauge progression (42-56-75-100) suggests this shouldn't be the case. So I'm wondering if they never updated the tension numbers on their website when they changed the A string gauge from .070 to .075.
Basically, their quoted tension numbers are very similar to the TIJFs with their notoriously too-thin-and-floppy .070 A string. Other than the A string, the gauges for the LTFs and TIJFs are nearly identical, and the tension figures are also very similar. So I'm guessing that the tension numbers for the LTFs are outdated and in fact, the set is more balanced in tension than those numbers indicate. They feel more balanced than the TIs (which would be pretty balanced in their own right if it weren't for the A).
