While I was looking at the huge JBPs, I also found some trees labeled as "Mountain Pine - Pinus murriyana". They looked like they might be good bonsai material, small compact needles and a fair amount of natural movement in the trunks.
I tried to search for that species, but the closest match I could find was Pinus contorta subsp. murrayana:

Assuming that this is what the nursery actually has (the description seems to match, and it would be a native for my area), are these generally good subjects for bonsai?
