Guys,
Don't let the XX concern you on the Blue Streak. There are several BSGers & TSGers that have played this shaft in a TM driver and they all say that the blue streak plays like an X-flex not an XX. The XX is misleading because it's not that stiff and the shallow bore in the TM drivers softens it anyway. If you can handle an X-flex in a TM driver, you can handle the blue streak. Run a search on BSG and type in "blue streak".
The tip section on my 660TR X-flex, Tipped 1" in my 510DF, feels stiffer than the tip section on the blue streak tipped ½” in my R7.
The blue streak is "Tour Only" very rare originally made for David Toms. Not many were made either.
Also, a Blue Streak Pull usually sells for $135.00-150.00 :surprize:
So, $100.00 shipped is a damn good deal. :)
Thanks
