I have assembled my last few builds with mostly the tools that i will have on hand during a tour, this helps determine if that tool is good if I should look for a better tool. This gives me more experience with my mini tool.

I also agree with others about not cutting the steer tube until it is dialed in. I tend not to cut steer tubes unless it is excessively long. I like the idea that I can raise the handlebars easily as i get older and the comfortable position is changing. You can also use excess steer tube for mounting additional accessories with an additional stem and handlebar section.
