I knit two rows with Telemark last night. It's much softer than WOTA, but it's still not as soft as the Merino. Then again I've only knit two rows (a total of 64 stitches) so it's not a real good review.
It is 100% wool and hand wash, so it would felt if you washed it. It's also a different weight than the WOTA. Did you look at Swish? That yarn is much softer, and you can wash it. I believe Swish and WOTA are both worsted, assuming that's what you want.
