monoleaf and bags

i have a sport trac and i have all the air management stuff but bags. anyway i saw a sport trac at the nashville southeastern mini truck nationals, it was bagged on 20's, with 2500's in front and monoed in rear with 2500' behind the axle. i was wondering what anyone thought of the whole mono leaf with overload thing. is it ok? does it ride decent? i would assume it should not be done for a long period of time though
