Hey, just my opinion, but for a board around 128x38, anything lighter than about 5 lbs/2.27 kg (including all the hardware) is starting to get too light. Any lighter and the damn thing will blow around too much when it's windy.
Then again, you can always add weight...
i doubt it was of much use to anyone else, but the last one was built solely for my needs and it fitted the bill perfectly.
Please tell us why you are talking about that board in the past-tense. I remember seeing pictures you posted quite a long while ago.
