I picked up C3s in gray to red for the narrower pods I sometimes run into. It was interesting to find that the 4 lobe blue totem is actually just as narrow in it's closest size match of the red c3. I thought this might be of interest for those whose local shops don't stock all of them:
Horizontal view showing the difference between the blue totem and red C3. Note how far down the lobe surface is on the totem, in an extremely small pod in granite the smaller total height of the C3 could make a difference?
Going down a size, I have a .2 x4, but went to a totem basic (blue alien) for my other double. This was partially just because the black totem was impossible to find, but also because the basic has a smaller profile, like the C3 vs. basic photo above.
