Hey! I saw your comment a while back but didn’t have time to address it at the time. It just popped back up in my head recently as I have been playing with my MC and MCMO and enjoying comparing how they differ. Note: I am planning to do a little write up about this soon to provide a comparison of the two, from my perspective. Edit: This review is now up: [Markmont. Classic Magnum Opus vs. OG Markmont. Classic](https://forums.yoyoexpert.com/t/my-perception-of-the-markmont-classic-magnum-opus-vs-the-og-markmont-classic/332969) -About the OD GZR: These editions were from when OD was beginning to make yoyos out of 7075 aluminum. You can read more about it here: [http://www.highspeedyoyo.com/reviews/n-z/one-drop-yoyos/one-drop-gzr-line](http://www.highspeedyoyo.com/reviews/n-z/one-drop-yoyos/one-drop-gzr-line) **Essentially, the GZRs are the exact same yoyo design, but machined in a denser aluminum, and are heavier than the original 6061 versions.** From what I understand, this is also comparable to how G2 does AL7 versions of their yoyos. From there, OD optimized redesigning a yoyo to take advantage of the unique properties of 7075 aluminum (higher strength and density) to provide a yoyo that is similar to the original design but altered with a tweaked weight distribution that provides a new throwing experience. **Despite the higher density of 7075, these versions can actually be similar in weight or lighter than the original, and will often have more rim weight.** Examples: the Kuntosh 5000qv, Seven Summits, Legendary Terrarian, and the Markmont. Classic Magnum Opus. Edit: As stated on the [Legendary Terrarian](https://onedropyoyos.com/yoyos/legendary-terrarian/) page, OD now refers to this procedure as “boosted.” In my opinion, optimizing designs to make the most out of the unique properties of 7075 aluminum is now a signature specialty of One Drop. They do it very well. --- _[View the full topic](https://forums.yoyoexpert.com/t/new-release-from-markmont-the-markmont-classic-magnum-opus/326007)._
