My Tip? Use it as much as you can! I had to sell mine to get a 200-400 but really wish I had both. Try some field sports if you don't already for practice.
I walk and cycle a lot with this lens and always use a Black Rapid shoulder strap for carrying. It works flawlessly and balances the body and lens very well.
Also bought a Don Zecklens Cap which I am very happy with.
Contrary to another writer above I always - always - use it with the hood on. All that glass up front and no protection? Hmmm... YMMV.
Finally, remember to microadjust. Mine needed just a twist on each of my bodies. However, almost only shooting wide open I could see it at once.
