My home inspection of Speedmaster heads

I always like to "wait and see". You never know. That's why I sit back and laugh when all the gurus post paragraph after paragraph of what they read out of books rather than real world experience. I also find it funny that they are always the ones who "seem" to have "hands on" experience with what seems to be everything under the sun. HA!
Wait and see = trial and error. Learn from it, read books and way the opinions of guru's.
One thing about guru's, get them around the table and most times they will reach common ground.
