This is what I keep in my bag: T3i, 50mm, Tamron 17-50, soon to be Canon 70-200, Go pro, Rode mic, Lav mic, 3 filters with cases, a zip up bag think of a bunch of misc cords, intervalometer, evra quick release, a few plastic bags, and a pocket knife. This is pretty much full. If you put in a little bit of thought into arranging it, you could probably fit more. There are 2 side pockets on the outside which arent big, but can fit a wallet, cell phone, manuals, filters, cords, ect. Then theres the medium sized pocket which can fit a laptop up to 15 inches. I dont find this pocket useful at all because its not really wide enough to put more equipment in. Theres a few zip up pockets in it where I put my batteries, memory cards, and go pro mounts. If you dont put a laptop or whatever in this pocket, you could for sure fit a small fleece, a neck warmer, and an extra pair of gloves if packed very neatly. If you have a big gatorade bottle, or water bottle, this might be difficult to find a place to put it. Im taking into consideration getting a camelback hydration pouch (just the pouch and not the packpack) and putting it in the medium sized pocket with a tube coming out for water. Only problem is, you have to make sure it will not leak or the shit thats in that medium sized pocket is fucked. You could also fit a few snack in some places. Its a great bag, the only thing it lacks is space for misc stuff IMO. But unless your touring in the BC, or going on hikes in alaska with survival kits, this is a great bag.
I love my tripod so far. On it I typically have the Canon t3i, Tamron 17-50 and the rode mic. I have not had any problems yet what so ever. If you plan on expanding to things such as matte boxes, rail systems, follow focus; I would recommend picking up the 501. I was in the debate about geting the 501 vs 701 and the 190 legs vs 055 legs. For the head, this really depends on your setup. If your not getting crazy with extra things on your camera, go for the 701. Its much smaller and compact, and have heard it works much better in the cold then the 501. For the leg, for sure get the 055XB legs. Went to my local camera store and tried out the 190 legs, hated them. There a little to flimsy for my liking. At least for video purposes. If you think you are going to be upgrading in the near future to a camcorder such as the HVX or EX1, ect, then take the Sachtler ace into consideration. But with just the 60D, the 701 will be fine, Like i said unless your getting crazy with attachments So if I were you, I would for sure go with the 701 and 055 XB legs. You wont be disappointed.
