Thank you all for the feedback. One correction, I was not looking to buy both, just been drooling over them and am undecided. For context I do a fair amount of work with 6/4 and 8/4. I am also a big guy at 6'3" and 250lbs., so weight and size are not an issue. Iwoirhaye - I actually love hand planing, it is a great workout and just something about connecting with the wood on that level is relaxing and rewarding. I invariably hand plane my joints before using the Domino as I have the full range from #7's on down to a #1. I think I will go with the 75 as the board thickness is moving me in that direction and I will definitely take track length into account. Again, thank you all. I have many Festool pieces and was just looking to add to the collection as I received an unexpected additional bonus at work. The wife and daughter have many projects they want done. My motto is "New Project, New Tool!"
