Thanks to all who have responded here. My new project, the AM 30% Extra 260, is getting 5955TG's all round. Should be here today.

This will make my "fleet" all 8611A's or 5955TG's, so I should be able to gather some good side-by-side data over time. 30% Yak - 8611A's, 30% Extra - 5955TG's.... should be interesting to observe.

Local friend has a programmer, so I'll be learning about that, also.

As far as "bench testing".... the 5955TG and 8611A seem pretty well competition for each other. Wish I'd known how rotten the stock 8411's would be on gassers before I tried 'em. Oh well.
