I am very new to track (4 race nights this season) at the same track as you, I am using a pair of Nitto B123aa (heat treated aluminum) which I got used. I feel like the drop in them is way to deep for me. Right now I'm just trying to dial in the fit of my bike but I will be considering changing them out next season. I will likely do one last race this year and might try out a strait pin seat post to see if that helps me get more comfortable in the drops.
