I am trying to buy a board this week and am extremely confused about board length. It seems like the boards range from 3'0" to 5'0". This is obviously a huge difference. Twin tips usually only vary by a few cm and kite surfboards by a few inches. Why the 2' variance for foilboards. Doesn't make any sense. I could understand if its your first time out or your first couple/few runs and you want a 4.5' or 5' board but whats the point of having a board this large after your first few runs? And is there any disadvantages to having a 3' or 3.5' board?
Also shape question. It seems everyone has their opinion on the nose shape. Some of the better foilers, especially the ones who surf their foil say pointed nose is the only way to go and many others and most stock/ standard foilboard designers have a more rounded or flat nose. What's the best?
