I have played with the taylormade burner and ft-5 for a signicant amount of time. I used the taylormade burner for abotu 3 months and found it to be very incosistant. Most of the incosistancy comes from the shaft. if you are going to consider the bruner driver i would seriously consider looking for a shaft upgrade.
The FT-5 is a good driver but the carbon composite insert certainly takes away from distance. I have hit the hibore xl and xls and can tell you it has an extremely hot face. The ball flies off the face when you hit it. I found it to be the least forgiving out of the three and defenetaly the wildest (but hands down furthest). I would tell you to look mostly at the ft-5 if your willing to lack a little distance for accuracy but if distance is your goal look at the hibore xls. If your willing to spend a little more money, the 2009 burner is a terrific club with a much hotter face and a thinner wall leading to a faster swing speed and more compressed sweet spot increasing distance drastically. They improved the stock shaft (even though it still isnt great). To conclude the most important thing to remember is that 70% of distance is correlated with the shaft so if your buying on ebay look for something with a upgraded shaft.
