The Feathers shave slightly differently, but if you are switching over you will adapt within a couple of shaves. They are great razors.
Another possible option would be to keep your traditional straight setup and buy a Parker disposable blade razor since they're only $20 and use regular DE blades )and can also be made to use Feather blades with a slight modification). I really enjoyed my Parker, but alas, it was confiscated at the airport in Osaka on a business trip a while back. The Parker isn't quite as sexy as the Feather (which is a solid piece of engineering), but it is every bit as effective, and suits your need without having to sell off your goodies to fund it's purchase.
One, two! One, two! and through and through...The vorpal blade went snicker-snack!
