Hello Brandon,
The community decided quite awhile ago, that the tiered plan is the best choice in nearly every trading circumstance, unless maybe you're make a few HUGE trades, instead of smaller ones with many partials. For most people, I'd expect them to see 1/3 of the cost in comms as apposed to the fixed plan.
As for what I believe Thor mentioned, if you don't intend to trade options, you can request that DAS swaps out options data for ARCA book L2. https://dastrader.com/docs/can-i-swap-the-options-feed-or-otc-feed-for-arca-book/
Also, as a member of BBT with DAS and IB, I would recommend requesting this free data add on package: https://bearbulltraders.com/request-special-das-package-for-ib-traders/
