Thanks for the comments folks will try to answer a few of the replies now.
coomber - I didn't use it myself but there was evidence of some wet oily stuff about half way down the part of the post that was stuck, I think that may have been from Andy's attempt at removal. To be honest I just wanted to get my slide hammer out for a play ASAP, it's been waiting for this for a couple of months!
Eche Beach - I was going to send you a link to this thread but looks like you found it by yourself. Thanks again for the frame, will make good use of it but I'm undecided on the build at the moment.
REKIBorter - Thanks for that link, not decided on cantis or Vs for this yet, might just get one in stock anyway.
LittleSkink - I'll weigh it and get back to you.
paddlingpool - Yes all made by myself in my "spare" time at work.
Think that's everyone's questions covered. If anyone's got a stuck seatpost and is around my neck of the woods you're welcome to come and have a bash. I'd also be happy to bring it along to any rides I go to, think the Peaks will be my next, all being well.
