I have used Snowbee XS lines since they first came on the market, however last year I was due a new line and with the price of the Snowbee XS now, I asked the same question as the OP. The vote was unanimous in favour of the Barrio Lines. I ordered a WF7F which arrived within 2 days. I found it to be an excellent line and fantastic value for money. However, after a couple of outings, I noticed that there was a 'rough section' starting to appear or should I say 'feel' on the line. I contacted Barrio and the next day a brand new line arrived, no quibble, no questions or even the damaged line to be sent back. I now have bought a few of the lines and they have been completely trouble free. Excellent Company to deal with, superb products at a great price.
I am in no way connected to the Company, but I know great service, when I am in receipt of it.
