Double jogging stroller...help!

Li

We currently have a bob fixed wheel and love it! But, with the new baby coming I am just not sure wether we want a tandem jogging stroller or a side by side and is there a superior product? We run a lot so the new stroller will get some wear and tear. Also, the streets where we live can be bumpy and have cracks so good shocks are a must. Any suggestions, recommendations or advice on what to avoid would be really appreciated.
