Hey y'all, need some help on shortboard sizes. Have been surfing for around 2-3 years I would say I am an intermediate surfer - can cutback top turn bottom turn etc nothing special. I was wondering which route I should take in terms of my next board. Preferably would like something that can turn easier and is more short boardy but need some guidance. My current board is 5'8 19 3/4 (not sure about thickness) but is about 28 litres and I find it a bit too large and is a bit too hard to turn. I was thinking about getting a shortboard- I previously tried a Bruce irons 6'0 around 18 (and again not sure about thickness) but i would say it had around 25-28 litres. It was great. Easier to turn, had a surprising amount of paddle power and easy to take off on. It felt quite a bit less bouyant which I would assume was from the distribution over the longer length. Confused at what kind of board I should go for next, shorter board around 5'6 with around 25 litres or a longer more shortboard style board. I just want a board that is going to be a step up for me and help me turn and improve my surfing. Thanks in advance

(hope I get a reply haha)
