Hi Buzz,
The first person I thought of to answer this question was Dave Whiteside (and of course, he answered). There are benefits to both types of shoes and Dave has proven that you can where the minimal shoe and run ultras. As for me, I am more of a Hoka guy. At 190 lbs, I need a shoe that will absorb the impact (or I need to change my running style – like Dave has). I wish you well.
