actually you can buy progressives that will go to 1.5 " i beleive, also you can buy nitro Hagens (pricey) and tell them the height you want and they will likley do it for you, i personlaly would not want to go below the 1.5 " thats pretty low unless you want to go to a rigid or something i guess. :-)
