Dynasty League - Halladay Trade Help

[huckfinn1972]

I'm in a 12-team dynasty league. Pitching scoring categories are W, CG, SV, K, ERA, WHIP, QS. We carryover a 30 player roster each year. Each Spring we have a 10-round supplemental draft for minor league players. If one of your minor league players is called up during the year you have a week to add him to your active roster, if he fails to get called up during the year you lose the rights ot him. Outside of Halladay and Lee the rest of my SP is questionable (especially for a Dynasty League). I've been thinking of trading Halladay while he still has a bunch of value in hopes of getting young arns that will bolster my pitching for the future, Should I continue to ride Halladay for the next few years or should I trade him and stock up on young talent? If I do trade Halladay who is reasonable to target?

My current pitcher roster is:

ACTIVE: Roy Halladay, Cliff Lee, Roy Oswalt, Carl Pavano, Ian Kennedy, Brett Myers, James Shields, Livan Hernandez, Jordan Zimmerman, Kyle Drabek, Heath Bell, Andrew Bailey, Matt Thornton, Tyler Clippard and Tim Stauffer.

FARM: Michael Pineda, Jordan Lyles, Mark Jordan

I would try and move Halladay. Not sure what you can get for him in return and who has enough to deal. But here are a few guys I would like to have in a dynasty league:

Felix
Kershaw
Price
Gallardo
Hanson
Gio Gonzalez
Scherzer
