I bought a 3 wood in the beginning of 2008. i tested a bunch, i actually went in thinking i was going to get the sumo2 3w. personally i did not like it all that much. did not seem as long or forgiving as the burner. I ended up testing a callaway, nike and taylormade and got the burner. That said, when i got on the course with it i couldnt hit it straight for anything. i took it out of my bag for a while and late summer i put it back in after more practice. my swing got alot better during the year because i was practicing and playing more golf. When i started using it again it became one of my favorite clubs to hit. Straight most of the time with a slight fade others. almost always in the fairway.
I dont think either are bad clubs, it comes down to personal preference. I am a high handicapper and i think confidence in equipt has alot to do with it for us.
