I have looked at all the LML posts I could find on various propeller configurations and tradeoffs for my LIVP TSIO 550 and think the situation is quite well documented and summarized in   http://lancaironline.net/lists/lml/Message/38218.html  

As a result I would like to look into a counterweighted Hartzell prop, but Lancair only shows part numbers for a non counterweighted and a fully feathering prop. Does anyone have a part number for the counterweighted version? I realize that the part number is generated by the hub/blade/etc configuration, but would like to get it right from someone who has one.

Also, any experience anyone would like to share on counterweighted configurations would be greatly appreciated. I flew a 310 I had ~ 1,000 hrs, so I have a pretty good feel for the feathering/accumulator configuration

Many Thanks

Regards
