Hi Alistair,
Good to hear from you, and hope all is well
Apologies for the silence, catching up!
Interesting question I have to say!
At first, I would not have seen a huge advantage to have snapfaps on the Quark... But! I saw one flying in May with them, and I have to say, it was quite nice!
In fairness, he had extra elevator also, not by a massive amount, but more nonetheless, and was doing flips with ease!
So, yes, why not trying
I would start with a 50% setup and see how it goes. On a switch so you can enable/disable it during your test
