You could also look into some intermediate steps: IKON and Works.
Yes the Ikons are great shocks. Their site list out the model number 7610-1296 shock, which is the chrome or black steel, But you can order the model number 7614-1296 which is the alloy body shock. That would fit nicely with your build.
You can order through customer service, or there is a guy who owns a Triumph dealer some where that many have ordered through (he is an Ikon dealer/rep) and gotten a decent price on.
I just can't see putting $1k shocks on the one these bikes. As one member here states it so elegantly - "its like buying a fur coat for a $10 hooker" is it really going to make that much of a difference?
