I have the 100mm f2 which I would say provides the best results behind the 70-200 L4. Quite frankly, I was looking to buy an 85mm but got a good deal on a factory refurb 100 I shoot indoor sports so 100 mm works well for me. In smaller areas I use the 50mm or 28mm primes. If I can or want to use a flash I have the zoom lens for general purpose.
