Here's my two cents worth. I was in the same predicament and came to the boards for advice, the majority saying upgrade to the G20's which I did last Sunday. My average was 71 - 1st round with the G20's I shot an 81 - sprayed balls everywhere.
The meter is a little faster - 3 as opposed to a 2 on the L33 Raptures I was using however the forgiveness drops from an 8 with the Raptures to a 5 with the G20's, so when you miss the ding your ball will drift, sometimes badly where it wouldn't with the Raptures.
I am getting used to them now and the last three 9 hole games have been 33 STA Front 9, 33 STA Back 9, 33 Olympic week 3 tourney.
I miss the forgiveness of the Raptures but love the distance and the high loft of the G20's. I still have some trepidation when I swing and until that leaves I will always think I should go back to the Raptures....they are still in my bag but have resisted the urge for now as I get more comfortable with the G20's.
Hope this helps in some way.
