There probably are not enough Redlines available to worry about chasing after one. The N41 is sweet -- Greg just took first place for the season with his in L.B. I'm doing well racing with ours (...hopefully better after the new headsail arrives, as mine's pretty sad).
There were a few T37 built with keels instead of centerboards. The T37 and C&C Landfall 38 were both on our short list. The Morgan is not in the same class for speed or handling.
