You're quite welcome. Now that I know you don't have a GPU, I volunteer to find you at least decent polys for the next few months of your factoring. They may not hit msieve's GPU-target range every time, but doing your poly selects beats LLR-cuda as a good use of my GPU.

Repeated searches in the C155+ region give me some incentive to learn how to test-sieve, which leads to fiddling with the knobs as Jason puts it. All useful knowledge, and possibly heading for a beginner-guide mid-level GNFS entry.

GPU ideas: Go cheap, just get anything that supports the right flavor of CUDA. Even a low-end current card will be 50-100x faster for stage 1, while using fewer watts than a $100+ card.
