Those that accuse Yr Right of being a troll need to stop being knobs and contribute to the discussion theyselves.
The man has contributed since early in the thread, which is contrary to the meaning of troll. You make yourself troll by posting specifically to insult the man.
If the discussion is too technical for you go over to the Truss thread and have happy ending with your fellow knobs there, creampuff and leadsled excepted
