firkin -
I have an 18" GS and a 21" Chitlangi. Both handle admirably well, although differently. Hard to explain the differences, but they are in their own special class as quick blades. Be sure to post your side-by-side when you have both, and the "new" has worn off.
BTW - Jag & Prem brought the Chitlangi to BirGorkha with their "test piece", which Yvsa owns. The kamis do these regional blade styles down to the last detail, and this may include dyed wood on the handle (at least that is how mine appeared - it had more than just excess rouge, and my other Durbas showed no signs of this). Chitlang is an old, old village and may have traditions of its' own, even to using red dye on items because of the copper mines there. Keep Ma Murphy's Oil soap handy, and let us know.
