[Closed] Fork help

Hi I'm looking at updating my fork, I'm around 205lbs with full gear on and ride mostly fast and hard downhill. I'm only looking at 180mm suspension on the fork so dual crown forks will need to be lowered. The forks I'm looking at (all around the same price and new) Boxxer R2C2 (lowered to 180), Boxxer RC with Elka, Totem RC2DH coil, Lyrik RC2dh coil 170mm or a 2006 NOS Fox 40 (I would love a 2012 model, but price is killing me)? All models are 2011 except the Fox. If anyone feel the biker profile fits them or has an opinion on the matter, please feel free to comment and advice. Cheers
