For me fishing related pressies need to be useful but also items that I'm not likely to buy due to being overpriced for what they are / surplus to actual need / expensive variants of what I already own eg
Jag Self Take Kit
Jack Prolite Storm Poles
Jag High Toppers
Jag Weigh Bar . . . . . infact most of the Jag range I don't already own so I can revel in its shininess as I blank . . .
A couple of bulk spools of PB Products Ghost Dragonfly Flurocarbon mainline
Several packs of Gardner Mugga Hooks in all sizes hand sharpened by Jason Hayward
Custom Angling Solutions Modulus River range eg - River sticks / Rod rests / Butt cups / Trotting River Bar etc
Best 'unwanted' pressie last year was a Trakker Powerflo Tap attachment for my water carrier (non carp anglers may indeed scoff) . . . .perfect easy single handed no mess water dispensation for endless cups of T . . . . would never have purchased this by principle alone however its actually a good bit of kit for session fishing
