The company Spectre doesn't make any true AN fittings/hose. Their merchandise is merely for cosmetic purposes (note the hose clamp within their fittings). I would NOT buy their hose, as the braided stainless is very thin (as in not dense) and has a tendency to separate showing the rubber hose underneath.
If you do want true AN lines, and you want them to look good, you are going to be spending close to the $350 you are trying to stay away from. The main reasons for this is that the AN hose is larger (-10) and the Triumph coolant system uses barb-type connecting points, which would require some trick AN adaptors that tend to be expensive. You could run the braided stainless hose right over the barb--like the stock rubber hose--and hose clamp it; however, this defeats the purpose of switching to AN and also, in my opinion, looks ugly. The other thing to remember is that when buying hose you have to buy it in long lengths--usually 10ft. As stated before, Earl's has been a leader in AN hose/fittings and I recommend them. Russell is also a reputable brand.
