Costar stabs have virtually no effect on feel.
Disagree strongly. Straight cherry man myself, so I agree with Tricheboars on that front.
I'm genuinely curious to know what you dislike about Costar stabs.
I guess where I'm coming from is that if I take a stabilized key like enter and mount it without a stabilizer, it feels exactly the same to me when I strike it in the center vs. when I have it mounted with a Costar stabilizer. When it's a Cherry stabilizer I feel mushiness when bottoming out unless the feet have been clipped.
Again, I use Cherry stabilizers on virtually all of my builds since they're much more readily available than Costar stabilizers. If I'm building the board from scratch it's a non-issue since I get to clip the feet and apply lube. If it's an OEM board that doesn't have the cutouts, then there's no quick fix unfortunately.
