Haven't used a Riflebasix but the Timney in my M77 MK II is superb.

And I say that generally NOT being a fan of Timney in normal M700 clone applications where I have trended towards Triggertech and Jewell for the most part.

It does however take a bit of hand fitting to get the 3pos safety working just right on the Ruger...

Experience is what you get when you don't get what you want.
