guys, Looking to find a good wand and/or boom set up for the Shurflo backpack sprayer I am going to purchase. I plan to treat 10-12 lawns this season, all smaller resi's (under 8k sq ft). Will spot treat some, but will inevitably have to blanket treat a few too due to weed pressure. Ideally, I want to be able to cover the open turf areas without waving the wand back and forth. (I have heard that the stock wand/tip with the Shurflo would probably not allow for this, and that you cannot change out the tips on this wand.). Wand waving just seems way too variable. Is there a wand/tip setup that will fit this sprayer that you would recommend? Or how about a mini-boom type deal? The one thing I worry about with a boom is that I cannot cover the tight areas or sensitive boundaries (like along landscaping). Thanks.
