2 on residential work is fine, been doing it that way nearly 5 years wfp. You just need to work out your routine. As you get going it comes naturally. You need to simply adjust to each property, when you arrive just take a minute or two to decide who is doing what - either one does tops while the other does bottoms or one stats nearest front other furthest round back. If it's a big property you can even work over and over with each other, we do. Just remember; when you get on site take a minute or two to decide who does what and then don't get in each others way. Oh and whatever your plan, make sure you keep your hose runs seperated so they don't end up crossed over when you try to reel in.
