Are your referring to the CS Korum reels?....£40 reels are never going to be comparable to the Daiwa £130 reels....I recently purchased 2 x CS 4000 reels and am actually disappointed. I had a pair of CS3000 which I brought at a show, and they are lovely for waggler and light feeder fishing, and very smooth and powerful when catching carp. I have been using Daiwa TDX3012 reels for my feeder fishing (30-70m with 30g-60g feeders) for a while, but two are now hard to wind in - always feels like my feeder hasn’t emptied and They obviously need servicing as 4-5 years old and well used.
I thought the CS 4000 would be a good choice to replace the Daiwa reels but I was wrong. The line lay with fine braid is poor and it looks like the spool should go down another 2-3mm as the braid doesn’t fill the top of the spool, and the line clip had cut through brand new 8-strand braid 3 times already. The first time I just flicked the rod top underwater to sink the braid and it cut, second time I was just hooking the braid behind the clip for storage, and in a festival this week, it cut trying to clip up at the start. I will order a pair of Daiwa TDR4012 reels and the CS4000 will probably become waggler reels.
I wouldn’t recommend for feeder fishing with braid.
