boy did you open a can of worms, every person has a different preference, and most will probably say its a very subjective topic and its up to you to decide.
Depending on when (and where, and if bought used), the default tip may vary.
When the OB-1s first came out, this was at least 2005 when I heard of them, the default tip at the time was single layered Triangle tip. Afterwards, around Mid 2006 or early 2007, they switched the default tip to Talisman M. After some delamination issues with the Talisman Tips, in 2008, they changed their default tip to Tiger Everest. Before the introduction of the OB-2, the label on the shaft was just the company logo. With the OB-2 came the labels of OB-1 and OB-2 below the logo on the shaft.
