Another interesting merge style is used by "Banks Power", the apparently very patented "power pickle", which is much like a conventional merge spike but looks fatter, presumably reducing cross-sectional area in the merge and thus keeping velocity up:

Call me cynical, but patenting "X but fatter" seems a lot like patenting "X but on a mobile device" as seems to be the vogue for software and user interfaces these days - there may be something more to it, of course, and I suppose novelty is always harder to judge in hindsight (the old 'anyone could have done that' vs 'did anyone do that?' argument). Not that merge *spike* design is that useful to me designing a tri-y, but there should be a few good ways to control cross-sectional area through the merge, using either internal elements ('merge spike' in a 2-way merge anyone?) or wall profiles (probably - but not necessarily - bulges along the edges where the tubes 'meet' along the merge) ...
