Hi Combat1
I have been using 6mm Microbore on two reels using two poles on 1 Sureflo pump with no trouble however I was advised to cut 30 metres off the 100 metre full length.
I have it rolled up behind the van seat ready to connect as an extension - not needed it yet.
I was also told that the microbore is outselling the minibore by about 10 to 1
