I have ‘Sorens’ rom on my DM. All that I was aware of it doing is making a second ‘lock freezes’ claw selection give super pops, so that players can’t spam that award and instead need to use and not-use it strategically. Other than that I set the claw difficulty up one level (need to go over the left inlane to light claw at start of ball, not just shoot the right ramp) and I feel like it’s a pretty solid tournament game. I really don’t like playing without the claw in tournaments (especially with the ‘claw difficulty’ on default) since it basically becomes a game of trying to avoid the right ramp for as long as possible (since the first award when the claw disabled is the lock freezes) and that ruins a lot of the other modes. Plus the claw gives a lot more strategic choices which I feel is always preferable.
Of course, if you’ve ever had claw issues, then reliability may trump all that
I’ll be using my DM in a local league night for the first time in a few months and I plan to leave it on, though I do worry about it having random issues. I recently went through and replaced all the optos and connectors involved and it’s been solid ever since, so I think leaving it on is reasonable.
