This is my two cents worth......please consider it just that. One of the benefits of the tubular chassis is the larger foot box or area. Pans fatigue. Limited suspension. Kevin and Mendeola do a killer job rebuilding the pans and putting some crazy great suspension on them. Tons of respect from me there. I love what we build. That is why we build it that way! So my vote goes tubular.
In the end, just buy one. I don't think anyone has ever hated their pan based car. Buy from who you feel comfortable with and provides an emphasis on the specific things that you consider valuable. Each of the providers believes in their niche!! Don't be afraid of building a kit!
