Point made guys!!! Am looking into a backpack just now. I guess that like everything in life, go with your gut instinct. Thanks
exactly, if you felt it was ok / safe, you would not have asked the question
deep down you knew the answer, just wanted / needed some1 to point it out
when i started i used a " hand pumped backpack , 20 quid worth " for some high stuff ( 2nd floor ) i did this specific job like that 2 or 3 times i forget now, it worked ok till i build the trolley system, ok now the battery backpacks are 100 quid, it wouldnt be so much of a issue, but if you dont have that 100 quid yet, a handpumped backpack sprayer works ( 20 quid ) and will enable you to do this job safely
