qotsarock I have the following 5-iron classics new in plastic;
Golfsmith Jetstream S-290
Snake Eyes Viper Tour
Also have a Snake Eyes Viper Ti-4 (2 weights in cavity) in good used condition as well.
Hesitated to post since I think you are still looking at these for single length, but the Snake Eyes in particular have weight ports to add weight to get you where you need to be (you might already be aware of that) and the Viper Ti-4 has the additional cavity weights.
Thought I'd throw it out there in case.
Come to think of it I also have a used Pinhawk 5i (first iteration of the clubhead with the more Spuzz-worthy graphics). It's lighter than their current offerings.
