Pex or copper in 90 degrees bend

What would be better to use coming out of BB hot water heat.Would the 90 be better in copper through the floor joist and then pick up the PEX-AI-PEX in straight a way.Or make the 90 bend with PEX-AI-PEX coming up through the floor joist and connecting a few inches after the 90 bend.If you use the PEX do you support it in the bend or after it so it doesn't move (thats if it does move at all when the pump starts-really don't know).

In my case, I used pex for the baseboards in the 2nd level of my house. For each of these I used the propex baseboard tees to connect to the baseboard, and used a corner bend support to bring the pex up through a hole in the floor. That way I was able to eliminate an elbow, and didn't have to sweat as many joints. I then was able to support the pipe at the corner brace.

Does that help answer the question?

A joint is little more than a leak waiting to happen... Pex uses metal supports to make the 90degree bends (holding the tubing securely) - though the radius of the bend can be a little big for some applications. If you can get away without a joint - I would suggest doing so....
