Thanks a lot for the comments/ feedback. I liked the comment about washing the string with clothes since I did not know about this. I actually did try yo-yo string and it did not go well for me because of the reasons you mentioned about thickness and so forth. I am actually thinking about buying the spin top upgrade kit sometime in the future, although I am not sure if it will allow me to modify my spin top from bearing tipped to fixed tipped. You mentioned you read this more of a spinners log, can you maybe tell me how I could have done this so that it can be considered more of a review?
Special thanks by the way for the Spin Top trick ladder video posted by you. I am slowly progressing through the tricks provided in the video and it has helped me know what types of tricks are possible.
