Gary, if you want I can put together a little "care package" for GNFS pre-configured for automatic use with Aliqueit. It's somewhat faster than msieve/yafu for anything C93 or greater, and I think you'd find that it allows you to go higher with much less difficulty.

Default GNFS: crossover is ~c90 (or maybe below)

According to this benchmark, you can make this at least c92 or even c90.

I am now done with 19278. I took this one a long ways (for me). It has a very nice 2^3 guide for anyone who wants it. Status:

19278; i=1066; sz 109; C105; +122; 2^3

Default 71082

After hitting a couple stubborn c90+, I am done with seq 71082. Put a fork in it, kaput, nada. If anyone wants to try it, feel free. It just started a downward trend. Might be a teaser...
