[X] Type-7 Regenerative (Prototype)
As much as I would like to not take anything here and keep the cost down, I'll vote for this to avoid getting a second Experimental component on the same ship.
I am seriously considering making the first ship of the next era a dedicated testbed sacrifice class. I'd really like to make one of these big ships relatively affordable to make, and the best way to do that while keeping quality is to get all of the prototyping out of the way first on other ships. Even the advanced for it's time Excelsior wasn't the first use for a few of its major systems IIRC.
