Hud,
I always used Sweetlands when they were in production, never had a problem with straightness, best arrow shaft ever made and heavy. The Alaskans were made with Alaskan Hemlock and they were good arrows but not as good as the Sweetlands, they were made using the original Sweetland machines which the new owners bought from the Sweetland estate and moved to Alaska, they only made them for a couple of years.
el greco, good luck in finding any in that heavy of a spine. I have two sets of 70/75 and no they are not for sale.
