I will not put down other heads...but for VPA's Terminators they are machined from a solid piece of metal, where a lot of other heads are either poured metal in molds or welded together...so for VPA's heads there are no welds to break, and solid metal is always stronger than poured or "casts" metal. That means they keep an edge longer, and due to tight tolerances in the machining process they are more uniform and for me at least they fly great. In fact when I first got the 100 gr heads for my compound I didn't have to change a single pin from my field points to my broadheads, probaby due to the cut out's on the blades. I like the cut on contact tip as well...just my .02 cents worth...again, there are a lot of great heads out there...I just like the VPA's which are fairly new to the market, and thought I would pass it along.

I guess to answer your questions best, order some and give them a try...
