Rick,
I have yet to find anything better then the 42 / 42 for me. But I just replaced a Roadsmart front on my 01, and it was terrible, I only got 8k out of her, and it was bad.
You were at the top of the max load, and your preasures seem to be in line with most on here. Maybe it is time to replace bearings, and do you have a front fork stabilizer on your bike. It gets me better handeling and better wear on the frints, but the Roadsmart I believe is just not a good match for the Concours. JMHO.
Hope this helps, ride safe all.
Greg
