If the UltraCut deck is the best deck you make, then why not put it on all of your models? You make a 52 UltraCut for the Lazer Z, why not put it on the the 52" Lazer HP? Now, I am not complaining about the cut of my 52" trivantage Lazer HP, its great and stripes well. But if there is something better, then why not make every mower you put out the best is can be. Your motto is "Nobody Does It Better." Stiving for the best? The increased airflow you get with the UltraCut would be nice on all units. It can't be a cost issue, the UltraCut is just a little deeper...right? Just a curious question. Thanks!
