I would like to see them getting away from the need for a wrist strap - it becomes problematical if you are in a sport that requires the use of forearm guards. Personally I would prefer a chest strap that could then connect with an electronic devise. There is a company that makes something like this, but they are so small they only have a very narrow range of sizes meant for A-B cup women.

Sorry for a partial hi-jack Helene, I would be curious to find out what you think of this if you get it. Wondering how adjustable it is and if it could possibly fit the ankle....hmmmm
