I would recommend you a rock shox sektor
I also own one (140mm travel 9mm axle) very pleased by it! before that I had a Reba for 4 years and it never failed on me (air fork), it made me a rock shox fan
the sektor is also available in 150mm version with 9mm axle, 15mm axle, 20mm axle and they all have adjustable ridehight (2 positions for the coil version, no idea for the air version)
I personally wouldn't put a 200mm fork on a frame that is made for a 160mm max fork (and the bike will look like it would be riding uphill all the time)
