I'm going to be sending my 25 t1 to mark within the next couple weeks. I got into a rock this spring trying to outrun a storm. It's not too bad but has a 1" section of one blade that is folded back, plus some other smaller dings. I got the prop used but in good shape. Do I just need to get it repaired, or would a b&b benefit me any? I have never had either done, so I'm a little hazy on the difference. I'm assuming the b&b just puts it back to the factory specs? Thanks.
