I can't tell you exactly,for your bow and you but I shoot that weight out of several bows and I would need 220-250 gr point with aluminum adapter to work on 29" 5575's.
For 2018's,I would need app. a 175 gr point with aluminum adapter.
Forget 7595s.You will need more than 400 grs up front,including insert.
I would start with one shaft,like the 5575 and change only point weight.You may be changing too many things at a time and just confusing the issue.I don't know what method of tuning you are using but I'd go to bowmaker.net and read that tuning information and note,he stresses-only change one thing at a time.
Shoot those 5575's with 220 gr heads.If they show too stiff,get some heavier heads.Start with 250's.You can customize head weights if you need too by using glue on field points with various weight adapters.Once you get it figured out with one set of arrows,that will help you figure out others,if you decide to change.
Just figure out the 5575's first.If you decide to switch to 3555's you would probably want to start with 75-100 grs less point weight than what worked best with the 5575's.
