Close, Rusty.
The Udhaipur has a full length fuller that lightens it up a bit. I believe the Chainpuri lacks the fuller. From holding your Chainpuris I would say that the feel of the Udhaipur and the Chainpuri is very similar.

Last summer I took some khukuris to a gathering of survival-type folks from Ron Hood's forum. Several guys were doing some chopping and splitting tests with their knives. I volunteered a khukuri. They took a look at a big 21"er and said "no way, that monster will chop anything." So they chose the lightest khukuri I had with me, the Udhaipur, as most comparable to the Busse's, Anacondas, etc, they were testing.
They chopped, they cut, they pounded the knives through logs to split them. The Udhaipur at least tied with the best of the other knives. Some would say the $30, scruffy, handforged village knife beat the high dollar products of modern technology. The reality was, everyone agreed that the differences between the top knives were so small as to be insignificant for practical purposes.
