I just had a set of meg Mo blades installed on my JD 757 w/60" deck, this afternoon. So, far I've cut 1 lawn with them and all I can say is wow. I'm able to throw the clippings twice as far, leaving no clumps at all. The clippings are less than half the size of when I ran the JD mulch kit. Seems to have good lift, I didn't have any stringers still standing and I didn't do any double cutting. Here is a picture of the blades. I'll post more in the future.
