You are right on the line between 400's and 340's. Here is the link to the Easton shaft selector sight: http://www.eastonarchery.com/products/selection-target

I would lean towards the 340, leave the shaft about 1/2" long (28") and a slightly heavier tip. That's the route I would take. Some would go the opposite direction, go with the shortest shaft and a lighter tip.

But the absolute best advice I could give, is shoot a 340 & 400 through paper and see which gives the best result. That usually isn't possible though.

For that cam, draw weight and shaft length I'd def think you would be underspined with the 400s so I'd go with the 340s.
