Thanks for your replies and advice. I used to be indecisive but now I just can't make my mind up!!!

I suppose that I will be happy with whichever choice that I make soundwise as they both must beat the sewing machine sound of the stock pipes. The local dealer has Thunderbike pipes on their demo machine but they haven't remapped and it backfires a fair bit (silly really as a demo should be perfect). I would just hate to spend that much money and then have chrome issues but I do prefer the slightly deeper sound of the Thunders. A decision will have to be made as It's booked in for its 800 K service tomorrow.
Thanks again for the replies, it all helps.
