Firm feel k frame reinforcement

Question to all who have reinforced a factory K-member: What is your opinion on the strength of a reinforced factory K-member compared to an aftermarket tubular K-member?
Which would you prefer to use for street use with torsion bar suspension?
I do not have either welding skills or equipment so would have to farm out my factory K-member for reinforcement.
Thanks in advance for your input and info.
It’s all only time and money.
It is likely that a modern tubular K frame would be stronger and lighter.
However, for what you spend for a modern tube K frame, you could spend that same money on a nice MiG welder and a few hours at a vocational school that teaches welding. And for about the same amount of money spent, you could have: your K frame reinforced, a MIG welder and the skill to know how to use it.
Saying that as a K frame is a great first welding project. Plenty thick so burn through issues will be minimal, and there’s no worry about pretty welds. You do want the weld job to be structurally sound, that is why I recommended some professional instruction.
