dt200 blaster vs banshee?

You cannot see the smoke ring with the thread still on, the electrode does not give a true indication. Only the smoke ring give accurate results.
 
why cant you just look at the electrode? that what my dad does and tells which way to go with jets.

No, the electrode will give an indication of cylinder temps but takes a very long hard run to burn it in.
The end of the insulator tells more about the plug heat.
On a new plug you can read soot deposition on the plug body, but takes a lot of experience to learn.
With a glass and a light you can peer down and read the smoke ring without cutting the plug but I can assure you that cutting the plug is the surest way to read your jetting.

A plug chop is the easiest, surest way to read jetting.
It will teach you how to use the other methods in time, but plug chops are where you start.
