It also had a nasty case of color shift with any exposures of 1/2 sec or longer. 1 or 2 seconds would get you about 10-20 points of magenta. I tried one or two rolls when it first came out, being a Kodachrome 25 user (and 64 when I really needed some speed), but I never bought more. Haven't tried any since, so don't know if it's reformulated or "improved".

I'd go with David's suggestion of pushed Provia, or even one of the Ektachrome 200's first.
