I'm too dumb/lazy to figure this out on my own. Carbon Matrix was just delivered. #3 cam, 30" DL, set at 60 lbs.
For the last 5 years I have been shooting Easton St. epic 340, 9.4 gpi, with 100 g tips with my Mathews LX. According to shaft selection guides, should I keep the same arrows, or buy something different? (I'm not looking for personal preference)

If you need additional info to answer the question, please let me know.

340 too stiff for that bow. I mean, you can get them to fly good out of it. But, 400 spine would be a better option

Have you tried them? Try them first and see if they work for you. I think they may be a bit over spined but with your length they should be just fine. Again try them you have NOTHING to loose.
If you think they may be a bit too much spine shoot them with a 125 grain tip that will weaken them some. But I always feel a tad stiff is better than a tad weak.:wink:

Tried them last night and couldn't get them to group like I recall with my LX. I will compare shooting 100 g and 125 g tonight and see if that makes a difference. Thanks.
