Spey - nice at low level, pretty bomb-proof, cr@p above block 3 (>40K+), draggy cos it's a wide bu@@er and made you look like you were crop-spraying if not in min burner. Oh and as already referred to - you could start it up without the crazy USN starter TRUCK needed for the J79.
J79B - not quite the thrust at low level, great though all the way up to well above the release to service limits (and nice dry power cruise above airliner-land), pretty bomb proof, the engine designed for the jet so nice and slim!!! = less draggy, Fast burner light if you enjoyed the hot relight bang and only made you look like you were nearly crop spraying. Nasty lack of volts if both stopped in flight though!
Oh and did I mention - You also got the US flying suit (one that fitted), spray painted helmet and black fin.
Where is 'gentleman John these days?
