Track frames look taller than road frames... thats what u mean? For sure use a frame 60 when u are like a 55 it will be tooooooooooo uncomfortable and slow to react... and usually for track u get a frame 1 cm smaller because u need a bike that should be stiff and fast to react and easy to manouver. Those are the usual rules. In my case I just go for 1 cm smaller than my road bike, Too small is too short and too big would result in a position too relaxed and when u r doing track racing thats the last thing u r looking for in a track frame. As u said... is a thing of preferences and u r a newbie in track.

I'll u give an stupid example... I was thinking in getting a ridley track frame, Well i had to send an email to the factory asking them because I barelly could figure it out what size was the right for me (not too big or not to small), I missed for half a centimeter from what the factore emailed me back. Im a little bit taller than ginetta and I use 56-57 frames but in ridley i have to go to 55 or maybe a 54. Althoug it is a thing of preferences and style it depends of the frame brand too, 10 years ago it wasnt so much as a problem as now it is... Sizing tables were done 100 years ago (im exagerating OK?) but with new tubes, new geometries, those tables only can be used as guide (in the past too but everything was more standar). So now u have to figure it out because even the sizing tables in the manufacturers web sites arent right at all (I imagine that the reason is because somebody can copy the angles and stuff).

cya...
