Oh watch out for that shaky history LOL
anyway i ride Sunshine 75% of the time with Revy, Kickinghorse and Red mixed in. I've been riding a sherlock 160 for 3 seasons but last year i rode the trick pony 162.
Its very similar to the sherlock as it floats pretty good in the pow. since its not as rockered i find that the nose doesn't pop up out of the snow quite as easily. i find its easier to land on it doesn't scoot out from under you as easy as the sherlock if you're in the back seat a bit too much. it will rise up pretty fast though if you kind of scoot it forward and pressure the tip thats in the snow .
i found the sherlock hooked around on me occasionally due to the very deep sidecut ( i pressume) especially if i landed toe edge heavy, but it usually wasn't a big deal since because of the rocker you could slide it back around without much thought. the trick pony still has this but not as much and its slightly less forgiving i found. it doesn't 'slide' around as much as the sherlock if that makes sense
if found ollieing on it easier than the sherlock, it seemed easier to pressure up the edges behind my back foot and snap off them if need be. again to be expected since its mostly flat
i found it was less squirrelly at very high speeds (like straight lining the flat part of delirium dive to get to the gully if i didn't make that stupid traverse on riders right lol). i find v rockered boards to get a bit unnerving at terminal velocity because for one i'm leaning back because i ride almost centered and two the rocker is pronounced. so at very high speeds going straight in pow really only half the board is in/on the snow. the trick pony is not as unnerving (but still nowhere near as nice as a malolo or something like that)
I never had any issues with the sherlock on groomed runs, and i don't really ride when its icy. i found them to be mostly indistinguishable in those conditions apart from the easier ollieing.
so to make a long story short i'd say if the sherlock is familiar to you you could describe the trick pony as a slight "more aggressive" version of it meaning it has less of the rocker looseness, slightly less float. slightly more response and stability. all of which would be expected i guess
hope that helps.
