sorry for my english
Get a Modify 100 spring, it'll get you around 370 with a bearing spring guide. 120 is too high for that target velocity, and is too risky as it can also get you up to 425fps at times, depending on the brand (120 is supposed to be 120 meters per second, which translates to just over 390fps). I've installed a few types of 110 springs (shoudl be close ot 360fps) and have gotten 410fps out of them at least (Madbull brand, think Guarder is the same).
