Thanks for all the responses. It sounds like they are both awesome arrows. I think I am going to try the FMJs. Thanks Again everyone!

If I get 400s cut at 28'' with 100gr tips and 3 4'' feathers for my 60lb Guardian @ 28in. will the spine be good?

400's with a 100gr. sounds right.

My experience with the fmj's was that they are great. I love them. No acc experience, but honestly, i would order some w/out ever even shooting them. From what everyone has said, they are probably the best arrow series ever made.

I shot the FMJ 400's out of my 60# Guardian. You'll be good to go.
