I am ordering some today, so I have been looking at them a little. I think the Superspine is a smaller vane that is mostly used for 3D shooting. It has a lower profile than the V-Maxx (doesn't extend as far out from the arrow). I will probably get both the 2.5" and 3" V-Maxx to see if there is any difference. At 8.99/100, I figure I can afford to get both. I've been shooting 4 2" Blazers on my hunting arrows, so either of the Vanetecs should do the job.
