I had similar issues with the Fluid Trainer; I did the Zwift beta on one and hated it. Having Direct Drive is sooo much better.
i am assuming I am within a handfull of watts compared to outdoors, but I haven't ridden outside since November due to the knee thing. I find out soon though, I know it feels close enough that I doubt the difference is all that big!
