HI,
I am only into my 4th week of wfp so some more experinced wfp may give you better advice, But I have been useing both 1/2" and 100mtr Microbore.
I love useing the m/bore compared with the 1/2", The 1/2" is heavy, Its hard to pull round all the many corners of a house, It gets snagged and caught far more.
The m/bore is very light to reel in, its far easier to pull round to the back of an house, I have never had it caught on anything yet, it is a joy to use.
It as a reduced flow rate compared to 1/2", But just good enough, thats on a 100mtr hose which I could cut down to improve flow rate or get a higher psi pump.
Nel.
