Depends on how much trigger pull you want, If you want the heavy 2 lb stuff then Timney is okay.
I have a Jard and a Kidd trigger assemblies. I like the Jard for it is a single stage and can be adjusted to a clean crisp pull.
The Kidd will run you another 100 dollars. Kidd first, Jard second, and after that anything else.
I have not used a Timney but it would be better than fiddling with all the other trigger parts and pieces.
