Welcome to the forum, Passing Time.
Problems with Felder and Hammer eh? Adam's put his finger on most people's problem with them.

Also narrow ravines guarded by whip toting archeologists can be a negative in extreme cases... Other than that, go right ahead and be generally considered to be a lucky >beep< for ever more :wink: Oh, you may find rust a minor drawback, but as long as you get all drooling passers-by to drool to one side you should be fine
Cheers, Alf
P.S. I seem to recall there's a Felder Owner's group out there somewhere, which could be worth tracking down.
