Ok guys as most of you know I was having horrific cutting problems with my super z. I tried everything and finally came up with the solution. I was forced to shim the rear of the center spindle 1/8" in order to level the center blade compared to the others. This cured the problem for the most part. Now I only see the problem in very thick/tall grass. Now for the title of the thread, I was using the stock xr7 high lift blades in the beginning of the season and they did fairly well, but they clogged up my deck like nothing else. I was getting so tired of cleaning it so I looked for other blade options. I considered using g6's made for the 66" pro master, but I like traditional blades. I settled on the new super high lifts for the 66" vx4. They are a notched high lift opposed to the solid sail high lifts from the xr7. This brings us to the good information. It has been raining extensively around here for the last couple of weeks and I have been so far behind, cutting some overgrown nasty stuff. Many of my properties are untreated and suffer from crabgrass and sedge when it's really wet. I have been overly impressed with these blades. They cut very well and really clean the deck as you mow. I will try to get some video of them doing their work this week. They do take some more juice to run, but I will trade that off to not have to scrape as much. This is just helpful information I thought I would share, I wasn't sure how many people have tried the new blades on the older decks.
