Ben is likley spot on...but you have options
If you are firm on 125 points and no weight added...1916 will likely be in your zone also.
If you want to play with point/adapter weight , arrow length, strike plate thickness, string material ....lots of others will work and you can look over the charts to see what kind of "total" arrow weight you will be looking at....
Small dia. thick wall are "hardy"
others to take note of ....1820...2013-2114/2115 ...even 2018 ....1820 is only avaiable in 29" length I believe. Its small dia. thick skin make it an excellent hunting arrow imho with shorter draw lengths .
I generally got them to fly great out of 40# recurves , but I think the PSR is built with more of a Longbow grip/shelf/rest ? If that is the case it would/could work as well .
As you know, a lot of factors go into what spine arrow works BEST for you and your setup , shelf cut ,shelf material thickness, STRING MATERIAL, release..etc...these are good starting points and considerations for some testing/tuning.
The 1916 & 2016 likely EXCELLENT starting points with best (on paper;) spines with those specs and keeping the nose weight @ 125 gr.....Both these arrows are avaliable in the cheaper tribute shafting.
Best with your quest my friend !
