I've been thinking of buying a Lazer Z HP. Although the mulching system looks like it would be far superior to any other design, occasionally I have to switch from mulching to discharge in the field. Seems to me it would be a good bit of work to switch back and forth. Please tell me it I'm wrong about this. One thought I had was how much would it kill the performance if you left out the baffle that makes each blade in it's own chamber? Running only the mulch blades and discharge block off. The UltraCut deck on the Lazer Z looks to have a pretty good baffle in it already. That brings me to my next question, what's the difference between the design of the UltraCut and TriVantage deck?
