Breaking when tuning up or when playing?
When tuning up it is a good idea to tune to C4 first, then over the next 1-2 days gradually tune up to D4.
I have a D4 on a 34" bass guitar and because it is close to break tension i do not string bend on it.
D4 on 34" is the same tension as G4 on a 25.5" guitar, right at the limit.

waltschwarzkopf,
Seeing that graph it seems you must know the gauges for a particular 'classic tuning light gauge' set.
I would be very interested to know these gauges, including which are plain steel, and roughly how old the set is, if you are happy to share this information.
I prefer low tension strings on a tapguitar, and would like to study SE's approach to this to help me develop my choice of gauges, but the gauges for a light Stick set is information i cannot find.

Oh, I just saw this, so I hope my answer doesn't arrive too late...

I'd be more than happy to share the gauges with you, also would be grateful if you could share any official gauges that you have

The gauges are as follow:

8 p
9 p
11 p
14 p
22 w

106 b
65 b
40 w
22 w
13 p
