I am looking to buy a lightweight fully waterproof brolly for sessions mainly on my local river but also occasionally on lakes that require a bit of walk to. I own a decent trolley but this is not practical on the river so need to travel as light as possible so I am looking at a brolly approx 2 kilo mark. The two tone Drennan one is out of stock which appeared ideal so I am thinking of the Middy Dri-sure 450, any opinions, options or recommendations please.
