AotI: 31+ Bullets and Techs

[MT7218]

Simple question: Does anyone know if and/or how much the PP costs for Techs and Bullets increase when they hit level 31+? And what are other effects of getting them to 31+, if they exist? I know they obviously increase in ATP/ATA, TP, and bigger and better range/visuals for techs, and ele % for all for hitting 31+, but do the SEs raise for some Techs and Bullets (I know SE5 doesn't exist, so rifles and bows won't go up there) for hitting 31+?

Here's some pretty complete info on the changes bullets undergo. (http://www.pso-world.com/viewtopic.php?topic=155747&forum=22&27)

As for techs, most of them stay put as far as SE goes, but a few get an increase. Barta and Zonde go to 2, and all the Dam-s get an increase of one on their original level. I'm not sure if that's all the tech changes; just the ones I know off hand.
