Congrat on the new machine! You will like it quite well I'm sure. I think you were smart to go with the std deck. The MOD works in the wet really well once you remove the two baffles underneath (Even the manual suggest removing them unless you plan to mulch a lot), but with them in, you will get some clumping. I doubt you'll notice the difference in power between the 930 and the 950 unless you regularly cut tall and thick grass. Then the 950 would be a bit better. My dealer was trying to sell me a 930 when I bought my 950, but I knew what I wanted and I stuck to my guns.
