I would think that part of it is the frames. The standard Next would transfer more of the input into motion. The UL framed Team Next would flex more and generate less drive from the same input.
My standard and UL Widow Makers are like that. The standard almost rotates around the lower spreader. The UL does big loops. Just the opposite of the Vendettas. The UL does tighter pitch moves than the standard.
