has anyone installed the unorthodox underdrive pulley yet? If so, any noticeable gains? Worth getting, or no?

IMO, the gains are marginal. The motor will idle a tad rougher. The worst part is that at low RPMs the alternator is not properly charging the battery. Also the water pump is turning slower so there possibly could be cooling problems.
