How many lbs are you shooting at now? Make sure those 400's are still ok at 70lbs. You might need to switch to the 340's.
I'm at 60 now...what do I look for with my 400's when I switch to 70? Getting ready to go to shop now. I mean...like how will I know if I have to switch to 340's?
You can enter your info into Bemans shaft selector to get an idea.

But I'm sure the pro-shop will be able to give you a definative answer.
