I don't trout fish even though I have access to some very fine trout fishing. But if I did, there would only be one method I'd use and that would be fly fishing.
My personal view would be to use any other method would just be fish catching, for catching sake. Fly fishing is a challenging art form to me and the challenge is more important to me than catching.
I couldn't agree more Phil.
If you want to fish for the sport then fly only!
As to other methods to break the Close Season rules, well, I'm sorry but I really wouldn't encourage that at all.
If you are that eager to catch coarse fish then please, try a stillwater where it is permissable.
I occasionally fish for trout with worm. It has nothing whatsoever to do with breaking closed season rules. The fact is that I'm not breaking any law or rule in doing so. However, I make sure that, where I'll use such methods, there is no chance whatsoever of catching and coarse fish. If there is a chance of catching coarse fish, I don't fish, even if the bye-law allows. Sadly that isn't the case for everyone.
Whilst the fluff chucking purists might get snotty about it, not that I give a stuff, catching a trout using a float and a worm is damned good sport.
