Does anyone ride with Modolo Dumbo Bars?

I need to get different bars for my Surley Long Haul Trucker .... I suffer from serious back injury, and need to have bars that allow for a more upright position.

I only ride a few miles a week, mostly to the store (about seven miles round trip), and work part-time a few days a month (usually about six to eight miles round trip).

I would like to give these handlebars a try, but would also like to hear from anyone who has actually used the Modolo Dumbo Bars ....

Thanks.
