I started off using WLP001 and eventually washed the yeast and kept it going. I ended up losing track of how many brews were made with each jar and had noted it was (can't recall the proper word) morphing as I was getting a bit higher attenuation.
We were moving and so I decided to dump my liquid strains and try dry in the meantime. US-05 was giving me the same attenuation but was leaving the sediment in the bottle compacted better. I don't care for too much yeast floating around and try to decant well enough. I've since washed this and am keeping it going instead.
I have read that it is the same strain, but have heard of flavors becoming present if fermented too cool or too warm, that it has a rather small window. I've only gone as low at 17.8 and as high as 19.4* without any issues.
