During my retrogrouch phase in the 90's, I went from racing with Dura-Ace STI to using Simplex retro friction downtube levers with Dura-ace derailleur and eventually to the SSC derailleurs when I got a hold of some NOS. Even during crit races, never had an issue with the shifting. The fact is the shifter makes a bigger difference follow by the Hyperglide cogs allowing the chain to ride on two cogs at the same time. The adjustable pulley cage just sweetened the feel.
