Has anyone used one of these bad boys yet?

I like how they offset the edges so the middle of the board isn’t crammed like many other boards.

I was planning on getting a Beastmaker, but the Grindstone looks to have more edge options (less pockets) and a general better layout with the offset design. I’d be interested to hear feedback from anyone who has used one and how they think it compares with the Beastmaker boards.

I've used both in the past and prefer the Tension hangboard because of the offset layout.  Both of them seem to be of higher quality than most, so i doubt you'll be disappointed with either.  The Tension Flashboard is also super nice for warming up at the crag.

I have their older Whetstone board and use a BM2k at the gym. Both have a nice finish and good radius to the edges. I'm not a fan of all the pockets on the BM2k, I think they're a waste of board space. I would rather have more full size edges to choose from, it's easy enough to drop fingers off to train pockets and won't let you cheat by getting up in the corners.
Also on the 2k the jump between the outer hold depths is massive. The upper is virtually a jug, about 1.5 pad depth. The smaller edge is 14mm deep, but due to the generous radius it feels more like a 10mm edge when I half crimp. I end up using the upper hold and sticking pieces of cardboard in there to make an in between one pad hold.

The only problem I had with the whetstone was that it didn't have a one pad edge, I bought two .75" holds from tension to supplement. They have that range covered on the new board with a 20mm edge.

I’ve got a Grindstone Pro. Definitely a step above anything else I’ve used.

Are the four-finger slots on the Tension board wider than equivalent holds on the Beastmaker 2000? I have large hands and my fingers tend to stack on the Beastmaker 2000 four-finger slots (though the "small edge" on outside of the bottom row on the Beastmaker 1000 is wider and works just fine). I was hoping the Tension board would solve this issue. Thanks in advance for the input.

I have the tension flashboard and carry it when I'm on the road for work (like right now) and won't be able to climb, just to slow my strength loss. I'm not impressed, but haven't been able to find anything else as small, light and easy to use on the road. 

Maybe their other offerings are better. 


I am amused by the grindstone and grindstone pro hold sizes being measured in metric vs the flashboard measures in freedom units.

What about the Flash board are you not impressed by? I've found mine to be well designed, well made, and very useful. Just curious about what issues you've found with it.

This is also my problem with the Beastmaker. The 2000 is mostly pockets where I would rather have edges. The 1000 has more edges but the upper row are super deep and not very useful. I’m probably going to go for the Tension instead since it has a much wider range of edge sizes to choose from. Glad to hear some positive feedback.

Guideline #1: Don't be a jerk.
