At £499 for the coil U-Turn Lyrik (which is a great fork, perhaps not as reliable as a Fox, but the damping works well and it's stiff), vs £730 for the Fox 36 Talas, do you really need to ask?
RS Lyrik Coil – New
RS can't be all that bad; after all they've more or less dominated DH racing the last 10 years. Yes my Lyriks did need replacing but they were replaced within five days and have since performed faultlessly for 9 months.
The other big advantage of Rock Shox (especially the coil Lyrik) is that they are so easy to maintain. Removing the lowers, cleaning and adding in fresh lube oil is a 15 minute job tops that even the most inept mechanic can undertake. Means you don't have to send them off at great expense.
