I have the same draw length and can shoot the arrows you describe out of the same weight bows just fine. You probably can't go super heavy on the point weight, but up to about 200 grains with aluminum inserts should work on most of your bows, and a little less point weight maybe on the heavier bows. You have to try them on your bows, but I am pretty sure you will be able to do fine with those arrows by just adjusting the point weights to the bows. If you want to shoot really heavy broadheads with brass inserts, you probably need to go up to the 250's.
I think you can get the aluminum collars from 3Rivers that fit at the point end behind the inserts. I know they are available for some shafts, like my AD Hammerheads, but I'm not sure if any of those sizes fit the 150's. I like the collars a lot, especially if you don't use brass inserts or if you are shooting at really tough objects. There are also nock end collars available from 3Rivers. I have not had any problem with the nock ends splitting using the standard push-in nocks with the CE Heritage arrows, although at times the nock may come out if you hit a very hard object like a rock, a concrete wall, a metal fence or even a stump. Therefore, I don't think you need to do collars or footing on the nock ends on those arrows, but you could if you wanted to. I have been very impressed with the Easton uni-bushings and g-nocks as far as durability and strength. I do think they help reinforce the nock end of the arrows. The problem with them is that once they are installed you will not easily be able to do anything to the rear of the arrow, such as cutting it to reduce arrow length, using a metal rod to help knock out front inserts, using extra weights that may screw in to the back of some inserts, adding weight tubes, etc. The g-nocks are rotatable to adjust fletching orientation, which is nice. I do not regret having them installed on my AD Hammerheads.
Just food for thought.
