trailing arms vs. a parallel 4 link...

[MMM...BRAINS...]

this is for my '49 chevy 1/2 ton on a s10 frame, static drop (no bags).

i'm playing with the idea of using a trailing arm set-up from later model trucks (i've got one laying around)

my question is if i were to use coil overs would there be an advantage/disadvantage to a trailing arm set-up vs. a parallel 4 link?

my goal is a daily driver (healthy 350/700r4 combo) that handles great and i can drive the snot out of

thanks.
