that 187 is an awesome weapon...... I also ordered the 180 from phil (and the dps 112- I doubt you need more but the 120 or 138 should be on the list) but if I skied in a more open environment, I would have gone with the 187 for sure. It's insanely stable and fun. It made me think I actually had some balls....
FWIW, I'm 6'1", 170, and am NOT the best skier on the mountain, whether I proclaim it for GNAR points or not. I ordered 180 Bonafides from Phil. And, to JayT's point, it's part of a planned 2 ski quiver and I will probably also find a pair of pow skis sometime during the season around 120+mm. The 180 Bonafides are also my "instructor" ski for skiing with my 5 y/o.
If I were the fastest skier on the mountain, and it was a OSQ, I would have ordered the Bonafides in a 187, per Phil's advice.
If you had been looking around a few weeks ago, I would have offered my Stockli XXXLs (formerly dawgcatching's - see his review of 88mm skis), as they are stout enough to handle the fastest skier on the mountain at 89mm waist and 178cm length and rip in crud. However, they are gone, gone, gone. You can find them on the internet, new, in a 178 or a 188 for about $375.
