Can't comment on the 10ft #8, but the GR70's are great rods. I believe they are built on the Hardy Swift MK II blanks which were cracking rods . I have the 11ft 6ins double handed Hardy and it's a great rod which I use regularly on smaller rivers. I will be taking it to Ireland in June.
The GR70 is being discontinued so there are plenty of good bargains about at the moment.
I am considering getting a 14ft #9 as a spare rod. I have been offered one with 40% discount.
Shop around and you should get a really good deal.
