Update, I've generated a .poly for 13^288+1 and msieve rates it's e-score as 4.429e-12 which is only slightly worse that the record for GNFS 152 (5.193e-12). So SNFS might be quicker since it saves...

f51_169m1 has built a matrix, with target_density=130. LA should finish in about 189 hours.
I seem to have underestimated the yield, so it's very oversieved (536,217,998 relations). -nc1 took...

Interesting numbers like 2^1277-1 are *much* harder than the numbers you are proposing as challenges. So it would need a *lot* of coins in the deadpool to make it worth factoring.

Thanks for the advice. I'll test sieve lims of 200M/200M against 133M/266M and see which gets the best yield. With luck I'll be able to post a job tomorrow.
