Hey Spazman,
Went surfing today on a new 6lb EPS shortboard I made and wanted to update this topic.
In recent years, most big guy shorties I’ve made/used were in the 7-7.5lb range and more recently I’ve made the switch to EPS.
After surfing my superlight today I confirm that RESPONSIVENESS is one of the keys to shortb speed but also totally agree with Halcyon that the other key is ACCELERATION. It felt like I got up to speed much quicker.
So bottom line…since youre accelerating quicker youre surfing faster more often. Top speed and how one approaches it, is another subject matter.
PS - with the lower swingweight, I even pulled a 360 at the end of a wave…havent done that in 15 years! Not bad for a 40 y/o dude.
