Thanks, always much appreciated when somebody shares some long term experience.
Im with you 100%, the 5 fin tip is unmatched. I tested all the new Ti tips for science and I can happily say just keep your old ones.
The new tips are not bad at all, just neither of them is better than the original when it comes to taste and function, they have a bigger margin for error though. The new 21 M tip paired with a copper sleeve is a beast for 1hitter glass setups!
The 7 fin is very similar to the 5 fin, but I dont see what the hassle is about, sold mine and dont regret it.
So in my book the perfect tip for most situations is the classic 5 fin Ti!
