Have been using these tips with B3P1 for over 2 months and prefer them even over the JVC Spiral dots with the Havi.
I have mentioned it sometime ago and this is the freshest post: http://www.head-fi.org/t/741221/havi-b3-pro-1-thread-2-0/1365#post_11963350
Glad to know that you discover them too. Seals better than spiral dots as well (YMMW). Thats one of the biggest reason for bass.
And dirt cheap too...
Haven't been keeping up with the Havi thread as much as I'd like (can only manage so many at a time), but concur with your analysis. My mileage does not vary this time.
