2563*2^5251511 is prime!
I seem to have much better luck on NPLB than CRUS. I wonder if this is just chance or if there's something unknown about prime distribution on base 2 vs other bases...

It's probably not so much about the base as it is about the fact that CRUS's k's are extremely biased towards the lowweight end of the spectrum: after all, there's a reason why they've held on as long as they have without a prime. NPLB, on the other hand, is searching a very large contiguous krange, which is quite ideal for finding lots of primes.
