Try cutting back on your dry hopping and add at 10mins/flame out as what you have certainly seems to be hop haze.Cheers- as you say great advice as always here, I do really appreciate it- as Phil said I will try the easier fixes first, a good rolling boil and some finings. I will mainly be brewing hoppy IPA's as that is what I like to drink so may have to concede they'll never be clear- the Cascade Citra IPA which wasn't clear when chilled had a 60g dry hop and 110g of hops in total. I had one last night from the garage and it was tasty and a nice straw colour, really taste is the main but clarity would be a bonus.
As @PhilBrew suggested using finings in the boil this will help. If your beer tastes good drink it but if your bottle conditioning a hoppy beer then it's drink it young and enjoy the flavour or let it age to clear and lose the aroma. Bitter sweet trade off unfortunately.
