I'm using Gilmour x-large sprinklers to irrigate the yard. Does it matter for the ones I use in full circle if it is long or short stroke? The short stroke seems to be only a little shorter in throw but much better distibution- I have very good head to head coverage if that makes a difference. These heads throw a great distance with good pressure. I have just started to use them on the short stroke and there doesn't seem to be any dry spots. Does it even matter? Thanks
