A ton forty
The Evolution darts certainly are unlike anything I've thrown before. They're a very dark “gun metal” colour with what appears to be an oxidised finish which I'm hoping will provide a good grip.
They spin perfectly true in a point protector block, indicating they've been well machined and pointed. Cheap darts don't do this, and give a wobble as you spin them in the block. I've often wondered if the wobble of cheap darts would give the benefit of a rifled effect when thrown (gyroscopically stabilizing them during flight), but I certainly feel better about darts which don't have the wobble.
They are shorter than my usual 5cm darts with Medium nylon stems attached. They're probably the same length as my usual darts with Short stems fitted, and of course with the Evolutions there is no option to alter the length due to their “all in one” design.
The first thing I checked was the flights end of the darts to see if there'd been any damage from incoming darts. They are fine though, with no damage at all. I must admit I'm nervous about causing any damage to them myself, as in the past I've wrecked a set of shafts in a single week. This isn't happening to me any more though, so maybe a combination of switching to 19's when the T20 is blocked and a better throw has developed over the last year.
At 17g (steel) They're a fair bit lighter than the 27g (95% tungsten alloy) I usually throw so they may not benefit me personally, but I'm going to give them a full and fair assessment.
