Hi I have Try-all fluro green 26" rims with no grind and zoo pads, they are deafening in a good way they are so loud neighbours come out of there houses to see what the commotion is . The original plan was get the rims for christmas then get them ground after but i have taken them through some pretty wet conditions and they have not slipped at all (YET) they are great, so if you want a loud squeak go for a smooth rim and a pair of zoo pads. Always remember that it is more important that the brakes work then squeak so if they squeak it is just a bonus. Hope it helps Dan Also i would like to add that i will proberbly not ride to much in wet conditions so i would recommend this more as a summer/dry set up .
