Hi Andrew
can see you made the right choice with the freedom trolley i have mine set on about half way, there is not much to say about it, its so simple to use one tip i can give you if youve got a bucket on a belt clip it to your 25ltr barrrel with your applicator in it thats if you dont like wearing it on your side like i dont. It saves a wet leg, just top it up every time you change your barrel this will save you carrying a large bucket about if youre doing trad downstairs
Where are you located?
Brett
