I went through two sets of Victoracers and two sets of Ecsta V700s on my Miata over the last two seasons. I know a lot of people might disagree with me (imagine that ), but I personally preferred the Ecsta V700s. They've got both a slightly different tread compound and a different overall construction with a more rounded shoulder as opposed ot the Victoracers. The two biggest things I preferred about the Ecsta V700s was the fact that they seemed to provide more consistent traction over their lifespan (I always found Victoracers to get hard & crusty about 2/3rds of the way to cord), and the rounder shoulder profile made for more progressive breakaway characteristics. A good thing for me, since I tend to drive a little "slideways".
Only major downside was that they don't last as long as Victoracers, maybe 2/3rds to 3/4ths the lifespan of Victoracers. Still, I say give 'em a try - I think you'll like them.
