Sure, no problem!
I have owned (since I started) the Rebel XSI, T1i, 7D, 5D, 5D2 and 5D3.
The rebels are what I learned on basically. The 7D was my first "pro-style" body. Loved the ergonomics, the performance, etc... The AF was excellent. I used it for everything! I bought a 5D to use along side it a year later or so when I was doing some events that helped with two bodies. I simply fell in love with the 5D. The detail, low noise, rendering, etc... Over the 7D images blew me away. But because the 5D was so old, it lacked much of the tech I liked about the 7D.
I sold both and ended up with the 5D2. Used it alone for the next year with great results. I had no problem using outer AF points, as long as they were in one-shot. Loved the high ISO performance and IQ over anything I have used previously. But I did miss having the ability to use point AF, expanded/zone, etc... Customizing the AF to cater to what I was shooting, etc... Looking back at the images I generally shoot at amusement parks, the 5D2 did well but had trouble with servo. They would be sharp, but never critically sharp in servo. If a ride support or something got in the way, the whole sequence would be thrown off.
The 5D3 came out and I was blown away by the specs. It was everything I wanted, and then some. Similar resolution, improved video integration, ever better high ISO performance (most of my shooting is probably at ISO 400 and above), the new microadjust (wide/tele), ergonomics, etc...
It was enough change over the 5D2 that made it worthwhile, and the performance has been incredible. The high ISO images are simply amazing, the AF is stunning and nothing really holds me back with this body anymore. The IQ is there, the AF is there, etc... There is nothing that I feel that would be better, unlike all the other bodies I have used. No matter how much I loved them.
I am confused on your wide angle statement with FF... I find the FF wide angle options much better than the crop sensors. I owned almost every WA option for my 7D with the Canon 10-22 being the best... (which would be 16mm on FF) - So your options include the 17-40, 16-35, 14L, etc... Quite a few options. For myself, I use the Samyang 14mm f/2.8 and my 24-105L for my wide work. The 14mm on FF would be like 8.75mm on a crop, which the only lens that I know of that does that is the Sigma 8-16. So you have plenty of really wide options with FF sensors.
To give you an idea of what I generally shoot, most of it is servo along with some other stuffs. 75% of my shooting I do at amusement parks with some shooting at the airport, events I go to, the zoo, etc... Pretty random stuff.
