MM - I assume you mean you are using the Triumph 4's? They are the most expensive, but you pretty much get what you pay for.
I have some Triumphs for longer road runs, but I use the Trigon Ride's for "bog standard" running - they are less cushioned, but a bit more "responsive" (i.e. it's easier to go a bit faster) - they do take quite a bit of wearing in though, but you can find them online a LOT cheaper than the Triumphs...
