yeah im at the beach this weekend and went to some shops. i was talking to a guy at one of them, and he said that, if they break, they generally make it clean and smooth and put plugs for removeable ones in it anyway.. and that, if you get hit hard enough to break a glass fin, that same force will generally pull the plugs out of the board anyway, so you'd still need to get it fixed.
sounds pretty good to me. this board has been repaired in two places.. one small ding on the upper half of the board, and quite a bit of fixing at the very tail of the board. it's kinda discolored, but he said he's surfed it last summer and this past winter without it leaking, so it should be good.
is there any way to easily check it when i get there to make sure that its sealed well? will just about any break make some of the board discolored, as water gets in right away? it's only discolored at the tail, so it looks like water didn't spread all over.. and maybe it's also partly the glass he put on there (repaired it himself, although he seems to know a shaper who says the repair is solid.. according to the guy selling it)
