Don’t remember or have the Jetstream Tour in our database. I looked up the Jetstream 2 and the images look like they were copying the Callaway X Series, but with a longer hosel. No idea how they would rate in the MPF without measuring them. If your nephew is new doesn’t care about “brands” and just needs some clubs, they may be fine. Kind of depends on what he is playing now as to whether they would be an upgrade or not. Most 16 year old players I know that play are very aware of brands and only want the Titleist, TaylorMade, Callaway’s, etc. Wish I could offer more help, but just don’t have the playability on that particular model.
Rlafoone, I would have to add cars to your list.
