P321 has a tandem option with 6 pawls. I'd talk to them and see if you're light enough to ride with 3. The regular version has unnecessarily high engagement IMO. It also only engages 2/6 pawls so I bet that running 3 pawls in the tandem version will be just fine.
standard version has 1.7 deg engagement
tandem has 2.5 deg engagement
tandem/2 is 5 deg.
DT 36T is 10 deg. And that's considered fast
DT 18T is 20deg. I have no issues with mine.
