My own lawns are of 150 sq metres on the front and 2 smaller areas at the back, I always use a grass box and empty onto compost heap. However for a friend of mine, who has a bigger lawn....grass..area.... I cut it once a fortnight for her without the grass box. So, mine is about appearance and quality and hers is about looking goood...ish....without being overly fussy. Both of us have healthy grass areas but mine is more of a "lawn". Kenc3, it seems you are happy with the healthy but not too fussy option so cut your grass without grass box. There are advantages too ...you dont need to feed and if we have a hot dry summer your lawn is mulched.
