I have my first static limb bow on order(stalker stick bows). Same weight as my other bows 52-3@27 and wondered if the static performance limbs require a stiffer arrow? Hmmm....

I found that going from dynammic to static on my stalker did not require much of a change.

In fine tunning I ended up 1/4 shorter.

Just depends, cut of riser etc. Bet your going to have fun finding out!

I have found no need to change my spine but my experience factors in what old goat2 said.
