The real reason RPM Cups are preferred is because the stock factory ones leave a bit too much slop and pop off quite easily in comparison to the RPMs.
At least that's what I've found to be the case. As well, I find the Kyosho and TLR Factory ball Cups to be about as good and firm fitting as the RPM variety.
Personally, having been a competitive racer almost 2 decades ago, we grew tired of popping ball cups and moved onto these and NEVER encountered any such issues. in fact they're still on my 20 year old RC10 and though all cruddy from years of living on a shelf, they're still in tact and fit as firmly as they did when new. Sadly I cannot find them in multi-packs the way I used to and as a result they are extremely costly. Still, buy these once and they pay for themselves in no time as you will likely never have to buy another set of cups again.
