I guess you mean 5-fin tip? For me, personally, the Omni tip is very good! It has a lot of flavour, even at higher temps and the risk of combustion is definitely less due to the added mass. With that said: I've sometimes found it difficult to get enough heat in the tip, especially when there's a slight breeze. Triple torches did the job for me (now using an IH though). The 5-fin tip on the other hand heats up and extracts quicker, the flavour is very good too but all things considered, I like the Omni tip moreWhat are the notable performance differences between the 2021 Omni Ti tip and the older 9 fin?
I've also never had issues with the OG cap coming off, is that the only reason to opt for the captive cap or are there other performance benefits?
The captive caps are really a non issue for me. I just squeeze them so the indents barely catch on the tip, they sit nice and tight and work fine. I never switch around tips and caps so I got used to it pretty quickly.
