apparentley there is very little different in the xt's to xtr's ,i personally would choose the xt's over the xtr's because of the power adjust and post mount.
Hope's are very nice, the new lever it great with the power and reach adjust easily hand operated. But expect the 'hope brakes are ****' from a few people on here.
id go with the hopes .
If you dont mind them not being bling hayes 9 are very reliable, good feel/power, extremely easy to bleed and pad changing is a breeze. they do a carbon lever version as well if you want a little bling
