They are stable for loads of different reasons
I had a traditional stripe indo that was stable in my tank for 4 months at 7" then it got to 10" and went unstable for 2 years and grew to 16"
I then sold it and it has been stable for nearly 1 year in a different tank
As for ST being so high priced well I think if you get a perfect 3 bar which is stable has a good body shape I would take that any day over a forked bar ST with messy stripes and not the same on both sides
People just want ST just for the sack of it even if it looks rubbish
To much focus on ST or IT you should price a tiger on what it looks like not what it is other yes what they are matters but not a fish like a tiger when most people can't tell if its IT or ST
