Some random advice

I glanced through a number of posts here which discuss the best options for various types of waves and surfers. There's so many variables depending on your ability and the type of waves you ride, so my comments here are probably aimed at a specific type of surfer, i.e. older beginner/intermediates, people (like me) who don't get to surf often, etc.
What I've learnt from 40 years of surfing is you have to base a board shape/dimensions on what works for you, not what's popular or what works for others. Luckily machine shapes are fairly accurate, so if you have to replace a gem, a machine duplicate isn't a complete hit and miss as it used to be with hand shapes.
I found a lot of surfers get hoaxed into surfing odd shapes like retro fishes, eggs, etc. I know there's many surfers who actually enjoy the whole retro thing and aren't into high performance, but if you want a board which complements or improves your surfing, get a traditional tried and tested high performance shape.
I went from surfing competitively and freesurfing a lot to surfing only a few times a month (since about 2010). So now I'm in a place where I'm unfit and feel like a complete kook, but on a wave my head tells me to do things I can't anymore. I've tried all kinds of boards in the last six years and found the worst boards for my surfing are the retro fishes and other wide/short/odd shapes. Sure you get heaps of speed and it's easy paddling, but decent carving is sacrificed. If you're an older beginner/intermediate or someone who doesn't get in the water much, hands down the best option is to take a high performance shape and ad some width and/or meat. Perhaps some trial and error to get the right formula, but so much better for your surfing if you want to move ahead or maintain a decent level. Not saying you shouldn't have some fun shapes in your quiver, but don't expect those to do much for your surfing.
I'm about 85kg, 6' and now mostly surf short boards between 5'11 - 6'1 x 19 (to 19 1/4) x 2 1/2. The width in the nose and tail is only slightly more than an average high performance board. 19 1/2 wide would be good of we often surfed chest/waist high waves, but we hardly do.
I used to ride 6'1 - 6'2 x 18 1/2 x 2 3/8 (with narrower nose/tail and tucked rails). Tried an old one the other day which was stored in my garage. What I noticed was that I had to work a lot harder on the wave, which actually resulted in a few of the best vert turns I've done in years, but the rest of the session was such hard work, not sure it was worth it.
