i would say depends on how much sag you have and how often you bottom your fork out
if you always bottom it out then yh for sure coz you dont want to damage the internal when you do some slieghly bigger stuff than you normally do
its depends on your style of riding really
+ its also depends on the weight of your bike etc
coz my mate have a .243 frame and some heavy stuff on it wif pike forks(firm spring), he weight less than 70kg, it was perfect for him and he still bottom out his on some harsh ride
