Tubular control arms?

[1969C10shortbed]

I know classicparts.com makes tubular upper and lower control arms as well as tubular trailing arms. Are there any advantages to having these on your truck? And if so are they worth putting money into getting them on my truck? I want to make it somewhat a good handling truck, and it's getting the small block treatment for now, until I get the 496 up and running together. Any input is greatly appreciated.

Thanks in advanced

Chris
