The new 800's helped me get a better deal on my 2010 1050

Ditto. I rode them both back to back...real world 90% road riding the 1050 is a clear value and better preforming. I have owned 3 generations of Triumph Sprints and the 1050 just gets it. The 800 is no slouch but no way is it a 1050.
I left the Sprint behind due to the Sprint GT is a purely a complaint driven remedy. The ST is a lighter, faster bike.
Triumph listened and cares what riders complaints are and are filling a void but imho..not an engineered 4th gen improvement.
The Tiger 1050 has better suspension and braking and ergo's over all of them.
