Given that I'm moving about a lot at the moment I've started training regularly on one of those portable fingerboards. I'm wondering if anyone has noticed any systematic differences between using the portables vs standard fixed?
For example, as I expected, it's a bit harder on a portable to get through the standard 7-3 repeater routine due to instability. I'm thinking this is probably a good thing, but it might not be. Also as a result of instability I'm mostly avoiding the two finger pockets—these seem much harder to hang than fixed equivalents, and I worry that the wobbling will result in tweaks. Instead, I'm thinking of starting to mix up weighted max hangs on the better edges.
