Freestyle-
The V-Force reeds and any aftermarket exhaust system are worthy mods to any bike. In my opinion, the V-Force reeds are the best bolt on performance engine mod once it's jetted correctly.
As far as the Renthal Twinwalls, coming from another rubber-mounted Honda owner, learn from my mistakes. I bought Atomic 22 big bar mounts, but because of the rubber mounts, they allow the bar mount legs to bend or become tweaked. I would invest in a complete quality upper triple clamp unit, such as a solid mount or the RG3 4-way rubber post system. I have TwinWalls, and I love them, but I'm on my 2nd set of Atomic 22 big bar mounts, and on both sets I have bent the legs on them (the part that bolts through the top clamp). It's like the bars are bent, but they're not, it's the bar clamp.
