You don't have a 100% or 110% spring (really don't exist in the % labelling unless made by PDI, and those are too low ranges to be PDI, I've never heard of them), you have a m/s spring, which is too strong for high speed gears to deal with properly, and the piston teeth are suffering from it. Another thing that kills piston teeth is a 9.6V large battery, ususally the assend of the piston gets ripped off, but shredded teeth happens too.
Largely decide what you want, high speed gears or lower fps, like inthe area of under 300fps, and move from there. But keeping the combination you have with the 370-400fps spring and the high speed gears............. prepare for many piston replacements.
