Unhappy in choosing prime sequence :)
Whatever sequence I choose I fail to find big prime (above 1.2M digits)
So right question is to change sequence when I reach some point, or to stick with few and be patient What is your suggestion/advice ?

Either you can look for light or heavy k sequences. Heavy has the advantage of the tests not taking as long. You might also consider a fixed n search.

how are you choosing the sequence? is it a polynomial , a recurrence, a special form like Mersennes? have you narrowed down the properties that may be stopping it from working ?

So for last one 4*53^n+1 nash weight is 585. Also there is 4*155 and 4*212 and so on. But also there is few sequences of base 10, where also ( regardless much more weight) Ihave no luck :) So I take various bases and various K :)

This reminds me of a Mork and Mindy episode where Mork goes to a bank to open an account:
Teller: Name? Mork: Mork, Teller: Is that your first name or last name? Mork: Yes.
