The question at hand has nothing to do with bostig gearing, only a suggestion for a transmission source. 
I can argue or educate anyone privately on either subject if you'd like to get ahold of me. 

I also suggest Daryl. He is the man.

>> I can put another recommendation for Daryl. Having just completed a Bostig (and since he's got a Bostig install himself), I asked him his advice on custom gearings. He talked me OUT of putting in a taller 3rd or 4th, despite the fact that it would have been extra money in his pocket. He shipped down a stock transmission and it arrived about a week later. I swapped out the old transmission and just shipped back my core in the box he used.
