First I want to make it clear, I know nothing about WP components (and very little about suspension in general, but learning :) ). So, that being said, I would like to test my gained understanding so far....
1. Do we need free bleed at all? I would say you no need free bleed. Without any, the piston would be forced to flow everything (we are talking a substantial volume and rate of flow here). That would mean ports would likely be quite large and seat pressures very low (in order to overcome initial movement).
2. Is more better than less? I would say that there must be a magic balance somewhere. Too much adn you would loose the accurate metering of the valve stack, too little and you would be getting into trying to flow too much oil through piston.
3. Too little free bleed be harder to set up? I would think so, as it, again it would put the "load" of adjustment onto the piston and stack and render clickers relatively ineffective, or at least less effective.
If I'm way off, I'll blame it on a lack of sleep last night...still a little dopey ;)
