I own a wooden 4x5 Tachihara and a metal 4x5 Sinar P. Comparing a wooden field camera to a metal monorail is like comparing apples to oranges. Before spending big bucks on an Arca Swiss I would buy a $200.00 Sinar F off of ebay and try it out for awhile. If the monorail seems right for you then sell the Sinar for around what you paid for it and then buy the Arca. Just a suggestion.
