That's what I'm looking for, thank you. I felt we would have to move from an 8" converter down to a 7" converter as well with this combo. Our current SLR is 9.05....I think that might be a bit light for the 312's manners, so the gear change would bring it to 10.91. That and the right 7" converter might be able to print some respectable 60ft times with the 4 link where it's happy.
