I broke my wrist at my first ever LTS lesson - after recovery I've used the Triple 8 wristsavers (not the roller derby wristsavers, just the regular wristsavers).
I would say you need this type to truly prevent a break after a bad fall (I've taken quite a few nasty wrist-first falls in these and felt nothing!) with the plastic that shock absorbs and spreads the impact of the fall. I had mine for 6 months (skating 5/6 times a week for 1+ hours) and have just replaced them as the velcro got a bit worn.
10/10 would recommend and have put others onto these at my rink and they agree it's saved them from some hugely nasty falls.
