Crux size 54 or 56

Dear Reddit,

I am in the process of buying a Crux, however I am not sure about the correct size. I tried both 54 and 56 in a shop and the smaller size just feels better, however the size chart puts me in the middle of the56 range. I am 179cm, long legs and short torso. On my previous bike (Canyon Grail M) I have the feelings that the reach is too long, and I cannot hold the hoods for a long time unless I push the saddle and tilt it forward. On a site comparing geometries, the 56 (+stem) is even bigger than the Grail (+80srem). I think I prefer smaller bikes, but don't want to end up with a bike too small. (I already had a bike too big in the past and it was awful.) What is your experience with this topic? Did anyone else with short torso size down?

Thanks for you help!

Edit: thank for all your help and comments! I was in the shop again, riding around on both sizes, measuring and comparing everything, then finally deciding for the 54 with a peace of mind.
