fractured the nose on my board 3 inches down back in october and fixed it myself... while i was playin around in the slop today it rebroke and came apart and i lost the nose, i was just going to glass it back up and say screw the front 3 inches.. any one have any feedback on how bad square noses are? like i said its only 3 inches so i didnt think it would be a big deal
I've seen plenty of noseless boards, I think you'll be fine. I have one that's missing about an inch and a half and I don't even notice it. The only problem I could think of is sinking the nose on steep drops but maybe you have another board for the steeper, barreling days anyway. I would say go for it and see how it rides.
Sand it, glass it, sand it again, surf it, and forget it. The tip of your board does nothing. Even if you lost a foot of nose I would do the same without any concern for altering the boards performance.
ps I can take off later on my 5'10'' then on my 6'4'' no doubt.
