I think the main reason you don't get the heated debate is that there are no toppers that are considered a "status symbol" with a devoted following. Lots of people like the kayfun/Russians but they are just not fanatical about it. Also there is nothing out there that people can definitively say "just get one now, you will eventually anyway".
Yes that's true; there's hardly any high end toppers;
there's the GP stuff, and the sophia; maybe if somebody puts out a cartotank with ego thread and airflow control and no chance of leak.....
