Ron,

I recently put up some crossed yagis with the ability to switch from RHCP to LHCP and I cannot recommend strongly enough that it is a real advantage to be able to do this.

Note that you would not T-Connect antennas with differing polarity...you want to be able to switch between them. You could do that with an antenna switch, either remote up near the antennas or in the shack...of course in the shack means you have to run two feedlines.

Another option is to build a relay switch as described here:

Which one should I get or should I order both and put a T connector between them ?

I have both the RHCP and LHCP receiver versions, but with a house move, I have not had the opportunity to test them.

Works OK with a good preamp. I have one mounted on my Explorer with some magnets from Harbor Freight, and an ARR preamp. Lots of guys here in deed-restricted communes, err, communities use them because of their stealth qualities.
