Twinings is not exactly the mercedes of English Breakfast teas but if you liked it before with your old difuser then why switch to another one? [my fave jasmine tea is 99 cents a box at my fave take out place so I'm not one to judge honestly
] The kind of difuser you're describing as your new one would be a 'better' difuser but if it's not making you a better cup I say pitch it [or put it in the cupboard] in favor of the old one! Who cares if it tastes good
