Thank you. Lynn E. Hanover In terms of Sound suppression and strength, the Spintech was my favorite. Only downside was weight (13 lbs) and draggy profile when mounted below the fuselage. It had flat surfaces but they were so well braced by the internal structure that they did not flex or 'ring' so failure was not likely. I flew it for about 200 hours on a turbo exhaust port 13B.
