Cortland Spectron

I have tried the cabela's ripcord si braid. It was 40 lb test a 10lb. mono diameter. It constantly broke during my cast. The low diameter i feel caused it to wrap under itself. I just read the recent post on the cortland spectron and it has a similar low diameter. I was wondering if amybody has experianced any similar problems with this type of line before i go purchase some?
Thanks inadvance,
