Bacterial artifical chromosomes and P1

Sat Sep 18 09:54:14 EST 1993

We have identified markers that are tightly linked to a viral
resistance gene.  We must obtain large DNA clones, and would rather
avoid YACs.  Anyone has any feedback on Bacterial Artificial Chromosomes
At what rate are clones obtained compared to YACs?  Their average size?
What vector do you recommend?
How about P1 clones?  They do not seem to have been used much?
Why not? (besides their size).

I'll summarize answers if I get enough response.
