Blades

[Scagman01a]

Oregon sells a high lift blade 91-638 and a super high lift 91-628. I cut about 2.5 acres every week, sometimes 5 acres if a neighbor is sick. The grass is nothing special mostly wire grass and weed grass. I don't bag. I have a scag 61 inch deck with a 27 hp kohler. Which blades do you guys suggest?
Thanks for the help.

The factory Scag blade does a nice job. However I purchased 12 aftermarket XHT blades off of ebay. The dealer sells them also, so I figure they should be OK. They are 10 bucks a piece shipped to my door. They look good the lift part of the blade is a little smaller but I figure they should cut the grass ok. Look the same otherwise.
I sharpened the original factory set for another year. I have the XHT blades hanging on a nail for another time.
