We had the Bob sport utility stroller and absolutely loved it. We sold it last spring and my son still whines about missing it, LOL. Very comfy for the kid and super easy to push. I really can't say enough about it. We used it daily for 3 years (we live in an area where we walk everywhere) in snow, rain, sun, everything and it still looked new when we sold it. I got a pretty good deal on it by buying the previous year's model after the new ones were released. And they resell very well. If you're really intending on taking it on trails or if you plan to ever run with it, I'd suggest going with the sport utility model over the revolution. The larger wheel in a fixed position is much better for that. The swivel wheel is nice for the mall, but not for trails or running. I had mine on the beach a few times as well and it rolled over the sand pretty well.
