I did promise myself not to tinker with the darts I have been using for the last two years, but I picked these up as a gift from the organisers in Bdos, and they are superb.
They are the same weight and length as my old ones (Hi-Tec, The Vice), but because of the incredibly high tungsten content (97% as opposed to the old 85%) they are ever so slightly slimmer. I've been using them since I got back, and although the bad shots are just as bad as always, when things go right with these it is incredible. I will definitely give them a full 3 months before even considering going back to the Hi-Tecs – there just seems to be nothing to lose.
The points are very well machined, and the darts spin in the point protector totally true. This is not the case with the cheaper Hi-Tecs, where there is a slight wobble. There are some very slight discrepancies between the three darts when it comes to the knurling, but any difference in the throw would be negligible beyond belief.
When they hit the board they just hit it with such authority. I really hope I can make these work for me. I think the real difference will be psychological though. I just love them so much I feel far more confident with them.
