Titanium vs steel retainers

[ekitch]

I thought titanium was stronger than steel, it is not, just lighter. Apparently steel is 30% stronger. Will a titanium retainer be okay in my street engine or should I go with a steel retainer? Has anyone heard of a failed retainer, I never have? I imagine it would be catastrophic if a valve fell into the cylinder.
I will be running an erson street solid roller cam with crower springs.
Thanks

Yes the titanium used to have the keepers pull thru--reason for the 10 degree super locks---the tool steel retainers are the best in my opinion

for a street engine anything will probbly do but stay away from the aluminum ones as the valve springs act like a hole saw on them and alum trash goes everywhere
