True story. I used Berkeley Big game for years, never let me down. I was fishing on the Wye for the second time and struggling. A certain Mr Trefor West came to talk to me and started to take the pee out of me( as he does) , but must have felt pity on the Northern numpty and told me exactly where I needed to cast to but I just couldn't hit the reflection on the river on the cast no matter how hard I tried.I was going to switch to a straight lead but TW wasn't having it. I had to get bait in.
I had a spare spool loaded with the Mimicry which I'd actually inherited when I bought a job lot of gear and never used ,so it was a gamble but needs must. Switched over from 15lb big game to 18lb low stretch mimicry and first cast, identical rod & reel set-up - I was on the money.
The difference in casting between the two lines was a good 25+ yards which was amazing really, but on that day was critical.
Found the pod and had some great sport. There was a lot of abuse on the line hauling good fish upstream through streamer reed ( when the Wye had weed!) at range. Plus regularly throwing 3-4oz loaded feeders on a pacy Wye which emptied them PDQ, also would take it's toll. Regularly checked the business end of the line , never had to cut it back all week, no malfunctions, worked brilliantly with a C3 . Have never looked back. It's all about confidence but sometimes a change can be necessary IMHO.
And who'd argue with Trefor??
