I am getting into fert/squirts this season - decided using a backpack sprayer to spray a few small resi lawns this summer to get started. I will not do a lot of blanket spraying with the BP - but as weed pressure demands, it may be necessary at times. The rest of the time, will just spot spray. At any rate - I was set on buying the Shurflo BP backpack, until I checked out the Fastpac system. I do like the option of getting the wand AND the gun with the sprayer - although it would be a little over $100 more to get the Fastpac vs the Shurflo. Any opinions out there on either one of these?
