26" vs 700c

the reason i ride a fixed trick frame -
most of them have already been said....

i like the fact i can run my seat slammed, but still do all the sitting down and flat ground tricks
i love the small back end, again with slammed wheel making wheelies all that easier
i like the fact that mines still a beaut to commute on (67 gear inches)
being able to choose between wheel sizes is pretty sweet
its LIGHT
i adore the way it looks
the headtube angle is lovely and steep, making nose pivots/manuals easier
(my seat tube is 50cm, the toptube is 54.5, headtube angle is 74 i think)
i like the choice of parts available for it
and most importantly its fixed gear :)

im not arguing that any of these reasons are valid by the way, just explaining my reasons for picking mine over a mtb frame. end of rant :)

I'm gonna pick your post apart but purely for the sake of the discussion.

You say you like that you can run the seat slammed but still do sitting down and flat ground tricks, how does that differ to a small frame with an extended seatpost?
Some might say a smaller frame with an extended post kept the frame out the way and made certain tricks easier.
Surely it's the placement of the seat that's important for the sit down tricks and general rideability of the bike but that seat is what makes the bike harder to tuck up under you like a bmx.
You say you like the tight back end and steep head angle for wheelies and nose tricks. What would you say if I told you that in flatland bmx where the bikes spend most of their time on only one wheel, steep headangles and short back ends were considered de'rigeur a few years ago but more recently these things have been slackened off because it's been found that a bike that's easy to get onto the front or rear wheel is not easy to keep there and that a slacker head angle/longer back end creates a larger balance point?
Is a sturdy trick bike really lighter than a mid level bmx? ( i say midlevel as it's possible to build ridiculously light bmxs but they won't be very sturdy and it's equally possible to find cheap bmx's that weigh around 40lbs)
