Hey Chrispy, I weight 88kg or so and I'm 53... around 5'10 and a bit tall. Probably carrying about 5 or 6 kg more than I need to and have never ever stretched as much as I should. I'm getting into the stretching caper now and I plan on getting below 85 kg again soon enough. I love the LB glide and I miss it on the shortboards. If I was getting out there all the time in decent waves, I'm sure I could go for fewer litres and down around 6'2. But for now, as I work on getting a quicker pop-up, the bigger shortboard is a nice cruisey way to go ... (and I got a great deal on the Puffer Fish.)
i would call it a medium rail.
funny i used to be a low rail nut. now im not so sure.
bushranger has a bulker rail but with that board its edged up further then most
