At my level of engine building and performance I have used/use
Comp Cams both hydraulic and solid link bar styles
Crane Cams hydraulic link bar style
I like these, the design is good and the weight is average if not slightly on the heavy side. I haven't heard or been told by anyone I know who did not like them or had serious issues with either. I'm sure there are instances of failure... they are massed produced and not every one is checked for quality and material control.
Ford makes one, but I've no idea how well they're designed or their strength.
Jesel makes a great link bar lifter, but they are considerably more expensive.
They are definitely lighter, but I have no idea if they are better in design over the top two other than they ARE lighter.
The point I'd like to make is that these aftermarket lifters offer better design and strength over the stock, spider guided lifters.
