Unparallel Qubit Regulus Newtro Comparison

Does anyone have experience with the Unparallel Qubit, Regulus and Newtro. The descriptions on their website aren’t the best. If anyone knows how the shoes compare in terms of stiffness, fit, aggressiveness and performance that would be great.

I have a narrower foot so I’d probably get the LV versions of the Qubit and Regulus. The Newtro says it has a lower volume heel which should work well for me.

Thanks.

I have had the TN Pro, Qubit, Flagship, and have tried on the Newtro. 

TN Pro is great, just wish it was a bit more sensitive. Good heel, performs as I would expect. Downturned, but stiff. The Qubit I hated, it is wider, clunky, and basically feels like a brick on my foot. The Newtro felt great, fit a bit more similar to the shape to the old Dragon, but stiffer. I would say it would be more sensitive than the TN Pro. Next time I order UP shoes, I will prob get the Newtro or maybe try the Flagship Pro. I liked the original Flagship, but did not love it. I felt like it lacked edging power, and feel like I'd rather wear the TN Pro or Drago's than the regular flagship.
