i've gone down the same avenue pj – kinda wanted more travel on my 5, well more than the pike, still have to be through axle and adjustable travel
options were 55 ATA, lyric coil u-turn, 36 talas, 2010 revelation 150mm u-turn, lyrik 2-step
ruled out the 55 cause of reliability, u-turn cause is a faff and my existing lyrik 2-steps have failed twice and quite weighty, sooooo got some new 2010 36 Talas forks on order through Progressive Bikes, much cheaper than anywhere else i could find
