custom chucks: to lace or not to lace?

I've been toying around the idea of custom designing a pair of Chucks on I love the the idea, I love the step-by-step process, I love the previews and I love the fact that I can have a yellow stripe in the back (try it!). I recently acquired this Hayden-Harnett Erol Bag from the recent sample sale and I used it as inspiration. The only problem is I cannot decide on whether to get a pair that slip on or lace up! I kind of like a cleaner look. What do you think?
