I have had  the slingshot 200 bag for a couple months.  Its ok if not going to carry much stuff.
  In the two months I have been playing with cameras and equitment I have now found the bag two small for my lens.   Especially the long lens.  I have the 400 mm f5.6 and will be buying the 70-200 f4 in couple weeks.
 I will then sell the slingshot 200 and buy the lowepro trekker II AW backpack that will carry more equitment. :)
  I have the Manafrotto 190XPro tripod and like it a lot.  I got the **Bogen-Manfrotto 486RC2 Compact Ball Head with RC2 Rapid Connect System which works great with my canon cmaera and 400 f5.6 lens.
 
I sent a bad copy of canon 100-400 lens back because of a problem with the IS in that lens.  I do want to get another copy a little later this year along with a Canon 40D body. :)
