How good does the 165 Khaos climb? As well as a 165 PRO? Is there anything to gain by swapping the Khaos rails to PRO rails or Ice Age equivalent? Would you have to change the front mounting holes if use PRO rails? Seen the Turcotte video comparing Khoas 155 to Khaos 165 with exact suspension settings and the 165 was in way more control while climbing and sidehilling.
