I've owned and flown a twin BVM Rafale, twin CJ F-18, A-10 and, am in the process of completing another twin CJ F-18. Enjoyed flying all of them immensely! That being said, KISS would still win out, in my book! If you can get enough thrust with a single to perform the way you want, you can't beat the simplicity and, when installed properly, the reliability.
