EF...is famous for being a tad heavy and short legged.
Famous where? I've never heard that assertion. Bear in mind it is te F-35B that has had weight concerns, not the Tiff.
Tiff in a standard fit with external tanks (let alone conformals if those come along) should have a comparable or greater endurance than a F-35B which, unless they've changed anything recently, has no wet wing points.
F-35B should be excellent and I hope we get it for both the RAF and RN's sake. However, the Typhoon is already proving an excellent and versatile aircraft, well ahead of anything else in service today other than the F-22.
The reality is that we need both, and they each compliment one another effectively.
