Backhalving?
I think a lot of it is depends on whether you plan to do it yourself or pay someone else to do the work for you.
I plan to backhalf my car just because I've never done one before and I like the idea of saying that I did it myself or with some help from a friend. I like trying new things that I've never done before, especially if it can be a learning experience. It sometimes costs me a little more from mistakes made, but I figure if I make a mistake once that costs me enough money I'll be sure not to make that mistake the next time. Do I need to backhalf; probably not? However, I will get the look I want and I figure a car running in the mid 6's in the 8th won't look too ridiculous backhalved and tubbed.
