4" rear drop - standard or super tracking bar?

[bsampson]

I'm converting a leaf spring to coil spring rear suspension on a '72. For a 4" rear coil spring drop, should I go with a standard or "super" tracking bar (the type that mounts below to passenger side trailing arm). I have a rear end with the mount for the standard bar, so that is not an issue.

Looking a ECE's stuff, I can get a standard adjustable bar for $60, or the super bar for $130 (includes U-Bolts - $40 value that I do need), making it a real difference of $30.

This will just be a weekend cruiser, but I don't mind spending $30 extra if it really is better.

Thoughts?
