if i understand you right you have a few fletched shafts at various spines (35-40lbs ; 40-45lbs ; 45-50 lbs) , and a few points at various weights you listed. Also i'm assuming your bow is "normal" 60-70 inches and 35-50 lbs draw weight..
i guess the short answer is "it doesn't matter" ( within reason) just find any combo that seems to work and stick with it. The shaft spine should match the bow draw weight, in general.
but... well, one other option is to match the point weight to the weight of the hunting point you will be using, if you will be hunting... 500 grains is a pretty standard hunting weight arrow, so you could go for the 150's cos that would bring the total near 500.
otherwise it probably doesn't matter much which point you use because once you find the shaft spine that goes with whatever one you choose, you'll be fine.
200 and 250 grain points sound way to heavy for most setups.
...or did you mean that all your shafts are spined the same and you have various points to test- if so , just start with the 100's and work up till you find what works.
