Opinions needed

Sorry in advance for the CTC-like post.....

I've got 28 days to spec and get a cycle to work voucher for a new bike. At the moment I have a hack bike, a langster, which is satisfactory for my daily commute. Considering the following options:

1. do nothing & keep the langster
   
2. Sell the langster and get something else
   
3. get a new bike and keep it for my sunday best
   
4. get a new bike and convert the langster to maybe a polo bike*
   
   

• I should add that though the idea of polo appeals, I've never summoned up the balls to turn up on sunday and try falling off repeatedly whilst everyone else falls about laughing ;-) (so presumably the conversion involves a 33 tooth rear cog, a pair of stabilisers and a kevlar bodysuit?)
  
  

what would you do and what would you buy? My initial reaction is go over to cavendish and spec up a BJ? To give this some context, I have owned some nice bikes and can tell the difference between a langster & a decent bike....

how about cyclefit, they could build you up a bling-bling machine for £1000. I can't remember the name of the bike in question though... someone posted about it on here recently.

Just keep the Lansgter

which cycle to work scheme is it?? With mine.. i could only order bikes through halfords..

'tis the normal scheme but I can use any retailer that will accept the voucher.

@asm: thanks for the tip, I'd forgotten about cyclefit... damn, those Colnago frames are pretty

There is no way I would turn down the offer to buy a really nice new bike really cheap through the cycle scheme. Hell, buy it, then sell at slightly discounted from full price and make a profit.

Or do anything but keep the frickin langster.
