I don't think 32" is short, it was considered long some time ago. I have the same length. But between brands there is quite some difference (e.g. dakine being shorter then MFC).
Most intermediate wavers are around this length. Some pros have longer (e.g. Pare), some shorter (TT), it all depends on feeling.
I think longer than 32" might be beneficial if you do one handed backloops, other then this I don't know what would be the benefit of going much longer.
I still love my 7.0 Unit (predecessor of the Turbo). For me it is the best biggest sail in a quiver, the session saver if the wind is below 16knt. Supper nice low end and it can still be rigged on my 430cm mast and wave boom. Once it reaches its limit on the upper end, I am already happily rigging my 5.3 blade.
Unfortunately they don't make it anymore, so hopefully it lasts.
