I just picked up a bob lee elite series takedown and it is a 56@27, I need to know which cx heritages I would need, the 150 or 250's. I wanna shoot a 125 grain magnus, a wrap, 5 inch feathers, and a lumanok. I need help thanks

Probably the 150s without a lot of weight up front.

i'm thinkging 150's too if you're not loading the front......I use 250's out of a 62# recurve with 250gr. up front.....

Depends on how far to or pass center your arrow shelf is cut.I shoot Heritage 250/145gr. point out of my [newer style]Bear Super Kodiak 55#@28.Got good arrow flight.Tryed brass inserts and heavier weight points because i like the idea of heavy arrows,but the arrows didn`t fly right.If you can,get or barrow one of each size and play around with differant weight points.Or you could call Bob Lee and ask what he thinks you should use.

Your specs are pretty much exactly what most of my bows are and my draw.  The 27 inch draw makes a lot of difference in the dynamic spine. You will need the 150s, even with 250 grains up front.

You would be advised to start with them uncut and work your way down.  I wasted a lot of money on carbons by cutting where I wanted them instead of leaving them long.
