I use a smitty. Because I once had the smitty loop break, I keep a noose with whistle in my jacket pocket....available at least for the first half. However, all the shirts I have now have a much more robust loop than the earlier shirts. I also have 3-4 backups in my bag.

my loop isnt thick enough to hold the smitty's on my shirt... idk if its too stretched out or what... but one day was enough for me

This happen to me too. One game, I forgot my Smitty before the start. I reach in bag to get it and guess what. All eyes was on me. I could not get the clip around the loop, and being that everyone was looking at me, I became nervous which compounded the problem. I eventually got it on but I think I tore up my loop in the process. It still worked but over time it eventually wore down. This little incident got me to using the noose. Just around your neck and away we go. No embarrassing moments struggling to get the little clip, clipped. I got fat oily fingers and sometimes it's a challenge.

Now, the 2nd problem. The loop on this particular shirt eventually wore down and my whistle went a-flyin. Now what we gonna do? Not a damn thing now because I got to finish this game. Having an extra Smitty was no help. This is when I realized how important that little loop was. I mean my whistle was flying all across the floor, I damn near lost it. Okay, I got a foul, where my whistle go. I was chucking that whistle 25 - 30 feet away. Go thru a few players feet and they kick it. What a pain. From then on, I got to have a noose and I keep an extra one for just in case it breaks.

Depending on the shirt, you can also run the noose thru the loop, which looks pretty slick and keeps it in place around the neck.

the only problem i have with the noose is that its hard to get over my head... i ahve a pretty big head, and the noose is just a lil too small. I wear a size 7 1/2 hat, so that noose is pretty tight gettin over my head
