What leadpipes do you guys use in your Conn SL-slide? And why?

I bought a Conn sl2547 slide with H, T and X leadpipes for my 8HT.
Just curious what leadpipe you use and why?

I use the T in my 2525 because, well, I don't use the X, and prefer the T over the H because the T makes it easier to get a centered tone.
