Triples is all about showing off a bigger sinep than SUs which can easily deliver all the road power needed. EFi is knowing that one's sinep is bigger but keeping it zipped up discreetly.
Drive both before staking your soul on the argument.
Both SUs, triples and EFI?
Triples look great, sound great and can flow more air than SUs and so can provide more power if thats what you want.
ITBs can match the power and will normally give better mpg.
No penii involved for me. I can't speak for you, but I very rarely think about them.
