So, got a few trips coming up this year and am looking for a backpack. I just got a Lowepro Rover 45L as a main bag but also need something a bit smaller to carry my gear around for the day.
I am going to carry my 1d3, 70-200, 28-70 and (hopefully) a 16-35. I may rent a long lens for a trip to Costa Rica later this year as well but not sure.
I know there a TON of backpacks for this sort of thing but I am also carrying my tripod. I use/prefer a nice heavy tripod like my Manfrotto and I use a geared head (also heavy). So I need something which I can carry my tripod on without worrying about whacking people around and worrying about it falling off while hiking.
Anyway, I'm a big dude but want a backpack that is somewhat compact although I'm not afraid of a little size if that's what I've got to do. I also would like something which may not make my back sweat off although I realize that may not be possible but, if there are better backpacks for that sort of thing, I'll take a look at them as well.
I've looked at the Thinktank Streetwalker and Streetwalker Pro bags online but, without being able to handle them, it's difficult to judge which would be better. I know the Pro version is made more for pro bodies (with grip) but it looks like my 1d3 would fit in the non-pro version as well but I can't tell for sure. The non-pro version would be a little more compact, which is why I'm looking at that.
Unfortunately, there isn't a good camera store around here (Jacksonville, FL) so I can't just go check them out. I used to live near NYC so I could hit B&H or one of the other camera stores in the area. I don't have that luxury here. 
Thanks.

). I find many backpacks just don't fit bigger people as well.
