Hi TC
I personally prefer no sprinklers in the lawn itself - noting to hit with the mower or edger. A friend has the traditional system - round flat disk full circles with quarters and halves at some edges. He is forever decapitating sprinkler heads with the edger and mower - tries to be careful but still sometimes hits.
Problem is the pipe is too shallow to allow for pop ups - so its a balancing act of getting the sprinkler high enough to spray but low enough to not be hit
We have no sprinklers in the lawn - just use a variety of moveable oscillating sprinklers. Have tried just about every type, wave ones are good but aren't easy to fix (I tripped and fell on one), the metal arm rotating ones and others
I bought one of these recently - sprays a good way and is adjustable to all degrees. https://www.bunnings.com.au/gardena-comfort-circular-spike-vario-sprinkler_p3120909
Also bought 10 of these when I worked out the price https://www.stratco.com.au/au/garden/watering-irrigation/plastic-pyramid-sprinkler/ (assuming it isn't just a WA clearance). Will be filling the hollow area underneath with cement to give it some weight.
Also have bought 4 of the traditional Pope Canberra 3 arm rotary sprinklers for $5 each last week - several bunnings have them on clearance due to Pope releasing a new 'click and go' head system that allows you to change the base to use a plastic impact, metal impact, bobble head, whirling vane and the 3 arm rotary - don't know why anyone would want to.
I have used 13mm pipe in all garden beds that are reticulated. Have used those small bubblers - they kept getting kicked and snapped. Starting to have issues with frangipani tree roots bending and snapping the t pieces.
