Assuming you are talking about the D Mini VX Ultra with the SST-50, there is no comparison. The throw of my Maelstrom is in another class it is so much better.

The G5 was designed from the drawing board as a thrower that can fit in your pocket or utility belt without the discomfort of a huge turbo head.Assuming you are talking about the D Mini VX Ultra with the SST-50, there is no comparison.
