If I were to upgrade to an SBD bowstring would it increase performance enough that I would have to jump up in arrow spine. I am kind of on the line between 1535 and 3555 arrows.
It did for me with a 6 strand, 1916 w/150 upfront to a 3555 w/175 upfront and 1/2" longer.
Yes it will. I bought an SBD string and it made my arrows shoot different.
Mine have all shot #10-15 stiffer when going from a fat D97 to skinny SBD.
I can. But may not. Depends on the change.
Mine also did slightly. I went to a skinny d97 from a 15 strand d97
Mine did. It changed it enough that my aluminum arrows were off but my carbons were not.
To me the string is the biggest single influence on the dynamic spine required...I have more than one bow that I have detuned with a B50 string so that I could use the arrow I want to shoot

The short answer is yes. Give the SBD Ultra a try and you will be impressed by the increased performance of your bow.
My opinion is no, but nock fit will show different reaction from your arrows..
In other words, if your nock fits tighter, or looser, it may show different reactions...
I noticed a difference when going from a dacron string to a low stretch string.Not a big change if any when changing to a different low stretch string materials.
Yup. Found this out the hard way when I was a newb. Changing string material can make a huge difference. SBD strings especially can make your arrows fly weak if you are right on the verge to start with. Serving size and nock for also has an effect.

Absolutely, if you're using a run of the mill string now. A quality string will allow your bow to be all she was meant to be. The 1535's are likely to be too weak if you're border line now.
Thanks for all the great information. I really appreciate it.
My Kodiak Deluxe bareshafts fine with 500 spine carbons and a B50 string...with a BCY-X string I shoot 340 spine...like I said a string can make a big difference for me

There are tons of variables to consider. You may have to swap arrows or point weight when changing to a different string. Will it be due to an performance difference? Comparing apples to apples, if you pick up 5 fps that is huge. Most people's release will vary about that much.
If you change silencers/silencer placement; if you swap from a glove to a tab or vice-versa; if you change nocks or serving size; if you change your brace height...all of these and more can affect arrow spine.
The only way to know if you will need different arrows is to try and see. The better you tune and the better/more consistent your release, the less chance you will need different arrows.
To check performance difference, shoot through a chronograph. That's usually an eye-opener for those who haven't done it.
