Sharkbite needs a push back fitting. I can always get the ring off with pliers and gentle turning on compression

Which compression fitting shut-off valve would you recommend? Brasscraft from Home Depot (the ball seems to be plastic) or the ones from Lowes (ball seems to be metal).....or none of them?

Dahl is a good brand. If you have time, order on line. http://www.supplyhouse.com/Supply-Stops-Risers-636000
HD and Lowes may carry some quality stuff, but more often than not, they carry items based on "lowest price" rather than "best quality".

The BrassCraft at Home Depot is Made in USA but has a plastic cylindrical "ball"; the Keeney at Lowe's is made in China but has a spherical metal "ball". Both are good enough so take your pick. I used the Keeney and it worked well.

I went to a plumbing supply store, and got "Everflow" valves that have metal balls - And they were cheaper than at HD or Lowes ($7 vs $9)
For the installation, I've read from 1/2 turn up to 2 full turn to properly tighten them.....2 full turns seems a lot !!!

Interesting; don't know everflow; wonder if they're good

They don't say much, including where they are made.

Grrr......Hope they are not junk !!!
I thought if they were sold at a plumbing supply store where pros buy material, I should be safe......

I've just installed 2 of them....the 1st one, I did a little less than a half turn, and on the other one a complete half turn
I have no leak at all......
But now I'm concerned about the valve being properly secured with a little less than 1/2" turn
Or if there is no leak, does it mean it's just fine?

In 30 years, I've broken one compression nut by over tightening. Is your valve tight on the pipe (can you rotate it?) If it is securely attached, it's probably good, but unless you're some kind of superman, you probably won't hurt anything with an extra half or quarter turn. You're using two wrenches, right?

No, I'm not superman.....I guess I'm normally constituted 
Maybe if I force on the vavle, I might be able to rotate it....But it's not loose for sure
I think the "problem" is I'm using straight valves, and I'm trying to keep the handle facing me
So the only way to grab the valve is from behind with a 10" pipe wrench. But the grab is not perfect with that type of wrench though
Now, I realize I should have turned the valve a little on one side to be able to use a 6" adjustable wrench
What is the risk if I try to rotate the valve to be able to use another wrench (6" adjustable), and then give it an additional 1/4 turn?

With the water off, you can loosen the compression nut and rotate the valve to the position you want, then tighten the nut. Most valve bodies and nuts fit standard SAE open end wrenches, so you may be able to find one with the open end at the desired angle to the handle.

That means a wrench with the open end being at 90 deg with the handle.....
Does this type of wrench exist?

If the crowsfoot or angle wrench does not match your situation, how about a photo of what you are trying to deal with.

What about locking pliers? Thats what I used to hold the valve. Locking pliers are great.

I think an angle wrench is what i need.......

Thanks to all the good advice.....Went to Harbor Freight and picked up a set of crowfoot wrenches. I used the 3/4" to tighten a little bit more the valve
Now I have made a good half turn, and it was pretty tight actually
I really don't see how I could go up to 1 full turn.....!!!!

You had already started with 1/2 turn, and you added another half turn. You gave it a lot of torque. It doesn't leak. I don't know if you said it, but I had the impression that it did not leak before you added that last half turn, right?
Done.

No, i completed to reach half turn ( maybe a little bit more, lets say 200 deg). And i found it was kind of tight to reach that half turn
