Forever, the 3555's were as weak as one could get in a wood grain arrow and many had found ways to make them work. I'm confident that if more guys would try the 1535's for draw weights up to 47#s (depending on draw length and shelf depth) they would find a new love.
In addition, the 1535's have been more available in the blems than the 3555's.
The CX 75's are great shafts too, but like the 90's they won't accept a weighted insert. This can be a limiting factor for tuning.
All the manufacturers have certain tolerance's when it comes to weight and spine of their shafts. Remember though that the spine testers give a static measurement and is not a true reflection of what is going on down range. Small variances in spine and even big variances in overall weight will have little affect in accuracy.
