Rope 'Um?

Itwill not get lost, have used it dozens of times. No need to worry.

Ditto for the Peridise. Have used them dozens of times; no worry.

I occasionally use some pretty big toys (think ~8" circumference) and all of my aneros models slip in quite easily. Considering that, I've never had a problem, or even really a fear of, losing the smallest peridise model. However, if it makes you feel more comfortable, then by all means attach a recovery string to the tempo. I would hate to be "that guy" that gave bad advice to "that guy" at the ER. lol

EDIT: By "slip in quite easily," I mean they slip into the proper position easily.

I think I will - at least until I gain some confidence. Don't know which would be worse- the ER or "Honey can you come here for a minute"?

I have had the unfortunate experience of having my butt swallow up the peridise. I was quite concerned and unhappy until I was able to somehow reach in and pull it out--it was not easy and mostly a matter of luck. I think the problem may have been too much lubrication, but I thought this couldn't happen until it did. I heartily agree with your caution.
