What is your draw length? What bow did you get? Can we see it?
We get excited about new bows!
If you are drawing 28", I would start with 1916 aluminum arrows cut to 29" and a 125 grain field tip. Any spine problems could be worked on by changing point weight. Your bow may even like a 2016, depending on its construction and string.
Practice a lot and ask a lot of questions.
I have learned more in six years of reading threads here and going to shoots than I did in the forty years of lonesome exploration I did before I found this site.
