I too grabbed one and will put it on my OSS handle. Little worried it may be too aggressive for me, but I'll gamble it.
I've tried almost all of the Feather Pro style razors. Even the more aggressive ones are fairly easy to shave with as long as you watch the pressure that you use. The less aggressive ones I seem to have more trouble with in using more pressure to compensate for the lack of efficiency. I think you'll like it as long as you listen to the razor, give it some respect and take your time. The beauty is in these much sharper Feather Pro style blades as they'll clear about three de passes worth of stubble in two passes.
