That's really interesting. Thanks for your input. I really wanted to go with SD7 levers but well, you made me think...
There has been so much experiencing by Atomz when they were made by Sunn with V-brakes it's crazy. That led to the ATS system the Jealousy still uses actually. So many factors can change the feel of the lever or the behaviour of the brake it's almost impossible to make the brake perfect for everyone. As you say the adjustment on the SD7 makes the brake spongier but it should also make it more more powerful. So it's always a compromise you have to choose. Some top riders like Robin Berchiatti for example prefer a spongier brake feeling with Hope brakes, others with HS33 and I don't know why. It's always down to personal preference I guess!
