I believe that they are OK.

The shot was at 25 feet.

That is a very strange shape... Do you know any pros or cons or this shape? It is cool but seems like extra work to get the same effect... :?

Some of my darts have tumbled for unknown reasons.

I am shooting them pretty fast and I want them to always fly straight.

Only time will tell if the hour glass shape is superior.

The sliced section has the potential to spin stabilize the dart.
