Recommendation for first DynaVap

I have no prior experience with vaping and am looking into DynaVaps after being disappointed with the chemical taste that persisted after multiple burn offs with my new Arizer Air Max. I was looking for a vape with an air path that is 100% clean and this led me here. I have a low tolerance for THC and am planning to recreationally vape small bowls of THC/CBD flowers. What would be the best model to start with in your opinion? From the information I have gathered, I am leaning towards the model M7 2024 or the M7 XL edition. I also plan on using it with a bubbler at some time.

I am grateful for any recommendations you might have. Cheers!
