Is 1/2" leaf spring relocation worth the trouble?

For what ever reason im leaning towards 18X10's
I have 17s with spacers on my 70 Duster with an A 8.25 and am comfortable with that. 255X15 on my 74 Duster with a 65/67 B. I have a 72 Demon with a 7.25 that I might swap one or the into it. The 72 needs some serious metal work in the rear so I might even just go for a 3" relocation, then the possibilities are endless :p
