In my opinion a pumpclip needs three things: the beer name, the brewery name and the ABV. The brewery logo may also be included if it's not too intrusive. Anything else is just superfluous. And all three of the required things should be clear enough and large enough to be read. I think that interesting shaped pumpclips are OK and that that can set a particular brewery's beers apart from others. A good example of a clear pumpclip with the necessary information is those from Milestone, whilst those from Leeds are clear and definitely distinctive.
The same principles apply for bottle labels. They should be kept plain and simple. The joy of a bottle is the opportunity to use the back label to really go to town. Standing in an off licence struggling to work out what is what is too much of a pain for a grouchy old drinker like me.
So to paraphrase, like my beer naming policy my labelling is going to be simple and traditional also. I just wish more brewers were like me.
