Honestly, I’d would wait for someone who knows what they are doing to give you proper advice but tbh… I tried growing my nails a bit.. it didn’t work out, personally I did not find it super hygienic.. then there is the option to grow the thumb nail but let’s face it, it’s a bit of a commitment and looks a bit odd.
I think if you are going for that professional stage performance you can either grow them or even get plastic nails stuck on.
For me I just have normal nails and if I need to do something which requires a nail specifically I have a thumb pick.
I think it would be near impossible to keep long nails with your line of work and probably uncomfortable.
Just my opinion not based on any particular knowledge 😎
