Hi all

I am new to photography, trying to decide to by a Lowpro Flip side or similar

200
300
or
400
or similar

Use a 7D , Tamron 17 to 50, Canon 100 - 400. also have a 70 - 250 Tamron
plus few leads filters adapters as required

Need to consider size and weight when checking in for air travel and having carry on, so usualy leave
the 70 to 250 at home
I have read lots of reviews. Still wondering. Any users of above out their able to assist in choice.

many thanks
