The New Yank and Bank is not doing its job.

I am a lover of pole fishing as well as most other styles, I have just moved out to the San Sai side of town and found a lake that holds a large head of Plaa Suai (Striped Cat fish I think) most are only around the two kilo mark. So, I figured I could use my newly shipped in Yank and Bank. These poles are designed for the comercial carp fisheries of the U.K. So they are meant to be able to handle large fish. But I am finding out, it is realy struggling to handle these little power houses. I lose every secound or third fish which is not the rate I want to be losing them...
I am going for the ton out of this lake and when I get it I will let you know..
