micro for home garden track

[cjm_2008]

as per the title, I'm looking for advise on which micro would work best in a back garden grass surface pravtIce sItuaIon, ideally 2wd.

it should be entertainingly quick but not obscene as the longest straight I can manage would be 12 metres.

the grass is pretty short but quite bumpy. I've tried my brushless micro sct out there and the poor thing just can't cope, though it's awesome in my new lounge!

are there any 1/18th scale buggies that I should be looking at for this?
