So i've had my Saber takedown bow for a couple of weeks now and am so far loving it. Today i decided to have a go at tuning the bow to get the arrow flying perfectly so i stripped the plastic fletchings of one of my cheap 30" armex arrows and had a go at bare shafting. I bought these arrows before i knew you had to buy specific arrows for certin bows and poundages.

Anyway, i think the spine is to heavy for my bow so i want to buy the correct arrows for my bow. Has anybody got any suggestions for what arrow to use? My Saber is 40# but i'm not sure what weight i'm pulling in at. Probably around 28". I've had a go at Eastons spine calculator but i was confused about the point weight?

Any help would be great.
