OK, I'll have to put in a vote for the T4 too. The captured pins are definitely an advantage, but what I really like about the T4 is the tranny. It's tough and will take whatever abuse you throw at it, provided that the regular maintenance is done.

If you happen to run across a really good deal on a factory team version, you can always just boil the arms. It will soften them up a bit and make them less brittle; otherwise, I'd go with the team version.
