JSC,
2-33's are still in use. Better than not having a glider.
However.
I recall that a number of G-103's have been PIO'd into the deck by pilot conversions from 2-33's.
A study presented at the SSA convention in 1997 showed that the US had a 30 percent churn in members, whereas the rest of the world was 20 percent. At the time, many clubs had few options after the 2-33, except perhaps a 1-26 and quite a few did not allow cross country in club equipment. I think few pilots used the 2-33 for their achievements. Many take pride in 1-26 achievements, as well they should.
Over 15 years ago, one of the larger US clubs made a decision to homogenize their fleet into G-103's, G-102's and an ASW-19 from a diverse fleet. This resulted in better pilots, improved checkride performance (according to examiners), and more rapid progression in the single seaters. I actually recall that they had an additional glider or two before this process started. They way US clubs operate, it's often a hurdle to get checked out for each glider.
Have a look at this PowerPoint that was presented at the SSA 2005 Convention Focus on Clubs Track.
