Based upon your description of yourself, 300 watts of resistance should be fine for longer intervals. Your current FTP is likely below 300.
Where it might come up short is if you're planning on doing shorter intervals, say 15 seconds to 1-2minutes, where you likely can do better than 300 watts.
Also, I'm not sure how the Keitler rollers data translates to non keitler rollers of similar size.
