I would get the 350's if it was me,it is better to shoot a slightly stiff arrow over one that is a little weak,I am shooting 64lbs and a 29" arrow and when I was trying to decide between the 250 and the 350 I shot the 350 and they were putting bullet holes in the paper,They are a tad stiff but I am going to put a 50 grn insert and see how it shoots then,I only bought 2 arrows until I make up my mind.I like a heavy setup and with the inserts I willbe around 480grn for my hunting arrows with close to 20% FOC.
