Third this notion! *BUUUUUMP*
I have a set and they are amazing. Though i do recommend shaving down the insert pegs a bit with a sharp knife(i used a pair of scissors), as they are an extremely tight fit otherwise. Felt like i was gonna break them if i fully seated them. Now they have a very smooth action and as stable as ever.
Will probably buy two next time if possible. They're an invaluable part of my gm arsenal now.
