Last winter I put the smoooothies in a 112H. I don't think they are any better or smoother thatn the stock HT100's. I was a bit disapointed after installing them.
I took the drag apart to find it was loaded with salt and grit. I cleaned it up and it seems to run smoothly now.
We'll see how it works if I hook in to a 40+ lb SBFT this weekend
