It depends on conditions aswell.
15 degrees, cold water, clouds, windy.. take the drysuit.
but 15 degrees, water between 15 and 20 degrees, sunny .. I’ll take my shortarm wettie
Between 10 and 15 I’m in my Pyro, so comfy.
When it is not really cold I’ll just put on my drysuit underlayers at the parking near the water so I have dry clothes on my way back home instead of swetty and smelling underlayer..
