Both players made all their titles on hard and indoor hard, but in my eyes Lu is the more in form player at the moment.
Kevin Kim had his best 2008 tournaments between mid of July and mid of September when he won Aptos, reached the final of Vancouver and won Tulsa. In the end of September he reached quarter final in Lubbock but then had 4 first round losses in a row to have a little comeback here, beating Adrian Cruciat and Rik de Voest in the first two rounds.
Yen-Hsun Lu played great in the first 5 months winning Waikoba, reaching semi final in Kyoto on carpet, reaching the finals in Busan (April tournament), Lanzarote and New Delhi (winning the first tournament and lost final of 2nd one).
He then fell in a little hole but had a great comeback this month winning Tashkent and going to semi final in Seoul.
H2H is 2-0 in the favour of Lu and I think tomorrow it will be 3-0.
