I vote for Slow swing meter but I am only a week old here. What do the vets say?
I guess it really depends on what you're looking for.... First let me say that there is generally an inverse relationship between Precision and Forgiveness in all the clubs in the proshop.... Meaning the more precise the club the larger the penalty when you miss the ding and vice versa. And also, for the most part, swing speed is also factored into it as well, usually the more precise the club, the faster the meter is going to go.
So if you want to be competetive, (and there are exceptions to this) you need to use irons with attributes like the i15s or G10s and you need to be able to ding, or close to it, every time.
If you are out to have a good time, and a good round with your friends and are happy with a GIR and 2-putt round, then clubs like the Raptures or K15s are the way to go.
Having said that, there are a few (not many) players that swear by the higher forgivness clubs and play very well with them, but you have to know them inside-out and be a stellar putter and recovery expert.
So as I see it, swing speed is really more of a by-product of the amount of precision and lack of forgiveness of a club, and if you can adapt easily to the higher speeds, then go with it.
Then of course there is cost...... but that's a topic entirely on its own.
Have fun!
