To be honest Newt, there are far too many "traditionalists" in the UK. I've lost count of the number of times I've turned up at a water with my lure kit, and some snotty match fisherman looks at me like I've got two heads. I see the questions forming in his mind "were's his put over pole? why hasn't he got a trolley with a seatbox the size of Guildford? were's his Carp bivvy? etc etc"
In all seriousness though, I think part of what is great about angling as a sport is the multitude of tackle and new ideas that can be used. Just because something isn't in a book or "accepted" it doesn't stop you from trying it (provided its legal and safe!).
I've been using soft plastic for a few years now, I've used everything from Crappie tubes to plastic shads and everything in between. I've caught mostly Pike and Perch, but I've also had Chub and large Roach on the small plastic insect type lures.
I'm always open to learning new fishing ideas, and although I wouldn't dream of ever using a Centrepin, I see no reason why someone couldn't successfully fish with soft plastic using one - soft plastics are just like any other form of bait!!!!
As for the comments about using any form of rod, why the hell not? My first fishing rod was a solid glass 7 foot spinning rod (heavy) and I used that for years for everything from spinning for mackerel to ledgering for Tench, and it never let me down.
Fishing is fishing, I enjoy just being at the waters edge (unless its bucketing it down like it is at the moment!)
