Replacing Brake Pads

The brake pads on my avid juicy 3's are getting very worn down and looks like I might have to replace them any day. CRC have 5 different types of pads for my brakes. Avid official ones with organic, sintered gold and organic with aluminium backplate. And pads made by "clarks" with organic and sintered gold.

Just wondering if there's much of a difference between the types especially considering the clarks pads are half the price?

Im just after changing my pads today,

I have juicy 5's and used the clarks organic ones.

I ended up going over the handle bars coming back into my house as i wasnt used to the new pads so they do the job alright.

They are reasonably priced aswell.

I'd go cheap and organic and replace often. I've ordered from these lads in the past. Sometimes they put a bit too much meat on them and they may need a little sand but work fine.
