Engineers are right out!

Engineers are right out!

That's going too far! 

I am not an hedonist nor a scientist...I dont indulge in gear price and appearence or in engineering ecstasy...

More knowledgeable on many aspects  than me for sure if i remember his posts...

Thank the gods. Scientist have no business in this arena.
