LS3 LS4 Differences

There has been much written about both of these gliders. If you use the search feature you'll hear this:
The 4 is arguably the best handling glider ever made with good performance. The 3/3a is perhaps an under rated value in the market. In strong conditions the 3/3a will go faster, otherwise the performance difference isn't worth chasing. Consider the trailer condition, aircraft condition and location in your interest level. The 3 has heavier wings, the 3a had slightly lower performance than the 3. Flaps on a first glider might be an unnecessary burden depending on your experience and skill level. If taken care of the finishes last 15-20 years it seems. Sanding and polishing will extend the life but many of the gliders from the 80's on are hurting right now. A refinish costs about as much as these airframes and there are only a handful of shops in the US that know what they are doing.
I say buy the nicest thing in your price range and find a reason to love it.. I never wanted an ASW-24, but guess what I'm flying these days?
Good luck and enjoy the hunt!

Thanks Doug!
Yes there is a lot of info on both LS3 and LS4 but I can find very little comparing the two directly.

Will definitely be looking for a ship with a good finish, or refinish. Hence the question about paint life span. Several of the gliders currently listed are advertising paint jobs from the 90’s.
Who are the trusted refinishing shops in the US?

Appreciate the info, Jason
