Often people in my gym tell me that slopers are for bouldering gym and that crimps are for climbing gym. Is true or not?
I think it depends on the routesetters and climbing in rock near where your routesetters train.
It is true that it can be seen in the routesetting of some Polish routesetters and therefore in the climbing gym where you can find lot’s of Pockets or crimps. But some of these routesetters do not rope and only bouldering, so set with a lot of slopers.
It is good in your gym to find routesetters who have a preference but you have to try to vary the type of routesetting.
It’s even better if they can work together where everyone can test the problem or the way of the other.
This allows to have a critical look at the setting and therefore to offer a higher quality routesetting.
So the best is, most often, if you can set with friends (with a good level will be better) and ask them their opinion. This will allow climbers who will climb (whether in a bouldering gym or a climbing gym) to enjoy the most of the climbing grips that the room has to offer to them.
