It seems that the extra stats are an every other series thing, like 35, 55, 75, 95. I know the 2 pieces of the 85 safe set I use for the buff bonus have no extra HP and SP on them. Most people completely ignore the 85 sets because they suck royally. I used my 75s until the late 80s and 90 greens, then got back to my 95 cross set. The 95 sets have the same stats as the 100 armors, with the addition of the bonus hp, sp, and crit on the boots, so I will use those until L108 at least. Hopefully will be able to make enough stones to enhance them by then.
