Hi. For Pollack spinning, in my opinion you can't beat deep spinning with a natural sandeel. Its a popular method down here in Cornwall. One plug pattern I have personally found to be effective is the Rapala Shadrap in the Firetiger colours. Also found that dark coloured jellyworms work well (the ones with a flat tail). Hope this helps.
Weeverboy says it all bass, I couldnt have answered it better allthough on rocky ground I prefer using jellyworms,there just as effective and there cheap if you are going to loose tackle on rough/kelpy ground
