What don't you like about the C3's?

Oh, different question altogether.

I threw out my Aliens long before the issues since I destroyed them on a yearly basis given the soft aluminum. They would keep mushrooming over and I'd keep filing the burrs off until I couldn't anymore. The C3's fit where nothing else works, they are smooth as butter and insert like a syringe, and I've taken countless 30fters onto the green 0 (atleast 10 on one route alone), and the purple 00 with them working with ease, and have only taken short falls onto the 000. The head width also gives them options to place where nothing else goes being atleast 20% narrower then the aliens.
