If only the
string makers would ask me that !

[and be prepared to follow through]
Now you realize that I do not have a Squier Mini-P, but that said, I like the feel and sound of the LaBella LT flats [42-100] which I got for my Hofner Ignition Club bass, and I have used GHS Brite Flats for many years, starting on my Ric during the 1970s when they made them for Dean Markley as Ground Round Wounds, so those would be on my 'Short List'.
I would continue to use flatwound or ground types.
Gauges for the Mini P ?
IMNSHO, the GHS Brite Flats are already a respectable gauge for SS [49-108, IIRC], so I might just ask for them to be custom wound to the proper length of around 30 or 31".
And for LaBella, I might try their 43-104 gauge DTF set, made shorter for the Mini-P, if I was working from gauges currently being produced, and LaBella already offers a wider variety of gauge choices in other scale lengths than most other makers do.
If I had to go in steps of 5 thousandths, I would likely begin with trying 45-60-80-105 for most 30" short scale basses, and possibly also for the Mini-P, for which 50-65-85-110 also might be considered.
For a long scale bass, I'm thinking 40-55-70-95 or 40-55-75-100, and already bought some LaBella [39-96] DTFs for my Ric, not yet tried - the Ric has had 45-56-77-98 Brite Flats [DM GRW] on it for many years.
