blue vs. scarlet flax?

Which do you prefer for linen: blue or scarlet flax?
Growing flax for the first time and have seeded both types to compare them later - any tips or hints greatly appreciated!

At my place, common flax, and Lewis flax grow very well. Scarlet flax struggles. Therefore, scarlet flax is my least preferred for linen.

I like both.  They seem to like different conditions, so it might be best to get a packet of both seeds.  Plant them side by each and see which does best in your conditions.  

@r ranson, which grows better in your growing zone?

I'm in Washington and starting with Blue flax this year. I'll pick up some Scarlet if it's better here.

Does your Lewis flax have a fine seed with an umbrella like lettuce seed?  That is what I have in my field.
I sent some to R. Ranson but I have not heard back if she tested it.
The seed heads of sme plants got wet before the wind dispersed them so I can pull a few seeds if someone wants to test it.
It gets taller where it remains wet longer. The field is clay with a 4 to six inch topsoil and has a large Z shaped saw;e pattern with shallow ponds. Where the soil drains fast or too far from the swale and ponds it may only grow a few inches tall and wait for the fall rains to bloom and seed.
A local basket weaver I trialing it for making baskets. The stems are very strong, stiff when dry and a nice read color.. It will grow tightly spaced and then has few side branches.

Lewis Flax has round-ish seed pods with black seeds inside. No parachute-like attachments.
