In AVA they had some pure 98 pcd too. But the problem is that the choices are really limited. Atleast 98-100 gives you more range to pick from (again in relation to pure 100s its limited). In my case my tyres & rims were almost through with their life. AVA had 2 options of 98 which I didnt like so had to go opt fo 98-100. Asthetically the extra holes dont really hamper the overall looks though I m not sure of the strength part that u mentioned.
