bam i have the bullets too i just added gaskets and they made a hell of a difference!
I think they are the same as the anarchy/bullet ones just with a different name, you will be fine, but if you find you love your knees even more you can either get gaskets or just upgrade your knee pads as its a very good deal!
cherry i had roces - there are a pair in hire now as i have new ones! they did me fine but you will need indoor wheels if you get them anyway! i would wait and save up rather than going in 3 steps as with the indoor wheels my roces only came about 20 quid short of the R3's anyway!
