I have not heard of Golden Eagle sleeves sinking in probably 4 years. They are still good and who I would personally have my motor sleeved by. That being said you won't go wrong with either Benson, GE, ERL, or AEBS. The only thing I would not do is buy the Darton sleeves direct and have a local machine shop install, that is asking for sunk sleeves, all the companies above have been doing sleeving for many years and have the process and materials down to a T.
