It's all been said by the other guys here and what might be worth a try is a brown Cavendish or just avoid it completely. Cavendish are usually used because they carry the topping or casings so very well but other flavour exist in different genres and it's worth exploring others for sure. ttps://www.tobaccoreviews.com has a search function that allows you to select tobaccos by varietal which is helpful and if you're looking for something with a very soft flavour maybe explore stoved Virginias like Rattray's Dark Fragrant, bit harder to keep lit but a very very subtle smoke. As to your original question, no, but I dislike the American style Aro's that have a lot more than just a topping or casing added and its possible that this is what isn't agreeing with you.
