Some questions about Sticks

I know someone will almost definitely tell me to “use the search function noob” but I tried and it got me nowhere so I’m starting this thread to get my questions answered.

I’m purchasing a JLF-TP-8Y-SK, now my question is; what is the difference between the JLF-TP-8Y-SK and the JLF-TP-8T and if you guys don’t mind try dumbing it down for a novice to the custom stick scene.

I’m also ordering an octagonal restrictor plate, would this be a smart investment?

Thank you :slight_smile:
