laminated birch question

[ThePushArchery]

I recently purchased a dozen Lam Birch shafts and I'm a little concerned that I bought the wrong spine.

I shoot 65-70 cedar shafts - 29" BOP - 145 gn tip. With this set-up I get great arrow flight out of all my bows and have very decent FOC.

I purchased 65-70 Lam birch shafts. In hind-sight maybe I should have got 70-75's and bumped up to a 160 or 190 gn tip to accomodate a good FOC.

Any suggestions on how to get good FOC with the shafts I have and not compromise the arrow flight?

(28" draw length, 52 - 55# bows)

Woodie Weights?  I've got some somewhere if you want them.

If you feel the need to get more weight up front, you can always glue on screw in adapters, then use what ever weight you want.  I use them with lam. birch for switching between judo points and fieldtips.
