Actually, I worded it wrong.
What I meant to say was that compared to the toes, the heel comes out in the back a little less than 1/4 inch. So roughly a 1/4 inch difference between the heel and toe.
But my toes and heels still evenly (almost) hang over the boards edge about an inch, give or take.
I think that should be fine, as long as it's approximate. Unless you're doing some very hard carving, I'm not sure you'll get drag. A wide board may help, but I wear a 7.5 boot and I get overhang on a 151 SL. The flip side is it gives you more leverage.
