Current Projects chat and miscellany

Hey,

I'm building up an old carlton (my first fixed and my first build). It has an old style seat post where the post and the clamp that locks it onto the seat are separate.

I was hoping to get a new-style adjustable one - ideally fluted or aero like these. The problem is its 25.4mm.

The question is should I:

1. keep looking for fluted/aero in 25.4mm;
   
2. buy a new plain adjustable seatpost b/c it will be lighter than my current setup;
   
3. keep the current setup; or
   
4. is there some clever way of changing the seattube size?
   
   

Also its a bugget build.

Advice very welcome.
