Man that looks awesome :tup:
An update, I stripped her down again and put the stock hammer spring back in... the problems are now solved!!!! YEAH!!!

Shoots nice... seems the Guarder hammer spring is too stiff, and i wasn't about to wait for it to soften up. Perhaps the Proud hammer spring would be a better solution? The stock spring performs well though so i think i'll stick with it for now.
btw, i've uploaded a video of it in action... check the first post. :tup:
