Turbo,
With a slow meter driver, I would almost say to go with the raptures, or wait a few more levels and go with the K15 set. The 9i distance of 200 yrds will last you a little longer than the G-10s. Meter consistency is important though, as I think you understand pretty well given your post.
I've been using the Lvl 49? Rapture irons for a while now and I like them, but I'm about to upgrade to the lvl 60? G-10 set. Eventually, you will have to go with faster meters, so why not get use to them sooner rather than later.
