Ed,
I happen to have a synthetic youth stock for an LT20 as I did exactly what HM is talking about and now that the 'youth' is full size I really don't need it. So if you happen to get an LT and you need a stock, I can make you a deal. (maybe not in time for XMAS).
By the way, you are making a great choice with the LT20. I bought the one I have now for my daughter and I kind of took it back for myself as it is a wonderful upland gun.
