Great bit of advice, Sean. I, too, have never used blue cheese unadulterated but I'm encouraged to give it a go.
I also have a slightly different mash-making method to you, which may be of great help on swims where it's hard to reach the water. I just put half a dozen slices of supermarket bread into the landing net then force it under the water by trapping the 'bag' of the floating bread under the rim, like this.
Just plunge it under for two seconds, then lift it out and wring it out in the net, which is great for getting an even consistency.
I was also interested in your comments about Drennan feeder rods - I have a Red Range Carp Feeder 11ft. It's the right length and power for chub and will, like the Puddle Chucker, handle moderate barbel. I have also noticed that Drennan now sells a Night Sight 1-4oz quiver tips separately, and that ALL Drennan quiver tips fit ALL Drennan feeder rods - very handy to know.
