RNWS Weight Cartridge

Was a little skeptical about whether these would work with my setup, but the 4-inch cartridge fit just as described and the transferable 5.5-inch portion is a nice bonus. Swapping weights between motors takes me under a minute now, which saves way more time than I expected.

The 5.5-inch cartridge is transferable between setups, which saved me from buying separate ones for each motor. Took a minute to get the fit right, but once it clicked, the weight swaps feel solid and dependable. Exactly what I needed for dialing in different loads without breaking the bank.

I was worried about compatibility, but the 5.5-inch cartridge transfers cleanly and locks tight enough that there's no wobble during setup. Being able to mix and match for different motor weights without buying whole new sets feels like a solid money-saver.
