REFLECTOR: Engine Selection

[J.P. Brooks]

Don, read "To The Man In The Arena" by T. Roosevelt.  Even if I (we) fail 
we won't be with those cold and timid souls like you who know neither 
victory or defeat.  Keep your money safe and in CD's and, if I were you, I 
would invest heavily in Lycoming stock.... that would be Textron.  You got 
4 million to throw?....  neither do I,.... anymore.... ;-).....   but 
should we succeed....hmmmmm?......
.....still won't be with you Don.
