Sometimes the riggers who are actually CRW dogs will be more helpfull in this department.
It is sad but there is a majority of riggers ( in my local encounters) that don't know a thing about Crw specific, swoop specific mods or gear. Worse they have no desire to learn or indulge this small portion of potential customer base. I've had to make my own toggles once or twice and enjoyed the process.
The hard question in CRW toggles is what you want as a lot of them are custom and the designs vary quite a bit. Not all dogs like the massive ones. Some are weighted so they stay put when you drop them. Most have something to keep the loop open for a quik grab.
One of my crw friend has fairly standard size toggles that have a section of cut away cable wrapped by the single layer of tape and sewn closed. Pretty straight forward, low profile but still CRW worthy.
