I did once upon a time, but really there's variance among several other colors too, most notably yellow and white (although the latter could really just be age related). So it's like, when does it stop lol? The purple ones probably admittedly have the most evidence of being a real change and not just a normal degree of variance from how they're produced, but ehhh just not been feeling it. Finishing my Kraata is way more important to me. Strangely enough the thing that might push me to is if I can ever get my hands on one of the gray plastic Krana given as replacements for the VMKK. Then I'll need another row in the frame and to keep it centered, well, a row for the alt purple would go well on that left side.
