I think I know what you mean Moonhead. I find that my Corbin is easier to get into the low setting than the higher one. I can locate the front quite easily but the difficulty seems to be in getting the rear of the seat lined up correctly with the locating dogs. It is a bit of a faff and I still haven't really got the hang of it. It does lock in place though, it just takes me a few minutes to get it right.
