Not convinced it made me a better rider. For a while it helped me push limits. I alternate between a full sus bigger bike and a long travel hardtail (that in reality is so capable) ride to ride. Thought process goes something like-
first week on full sus bike: well i did something last week just a little smaller on the hardtail so this slightly bigger jump/drop/whatever must be make-able with this bike
following week hard tail: well last week i managed it on the full suss bike and survived so it’ll probably be okay on the hardtail too.
and repeat.
That was until I had a couple of recent crashes which has slowed me down somewhat. The crashes were on the ‘forgiving’ big bike.
That said I would agree with this too so maybe did make me a better rider:
It makes you get your bum out of the saddle rather than bobble through sections in your comfy armchair as some do on a full sus bike
