question about bushings

[Smoothblack]

wanna get new bushings for my board (im riding the stock bushings right now and they suck). Im pretty set on venoms, however im not sure as to which ones i should get.
in short, i weight aprox 150 pounds and im riding a dervish (flex 1) i think i want a tighter ride then i have right now so i think ive settled on the barrel bushings (downhill) but which durometer should i get? thank you in advance.

90a should be fine if you want it tightish. Get the standard pack. Dervishes are most fun run on the loose side IMO, so I`d get 85a for your weight...
