I have a 2012 Specialized Tarmac with Sram Red.
Powertap rear wheel (on the heavy side)
Front wheel is profile design armada 42
Sram Red Cassette
Sram Red Crank
Speedplay Pedals/Cleats
Bontrager Lower End Shoes (were $90 brand new)

Problem I have right now is that I want to maintain my ability to train with power, but I know the best upgrade would be the wheels. Do I try to sell my powertap rear wheel, buy a crank based PM, and then go for wheels after that?

Thoughts? Where will I see the biggest bang for my buck?

I am a Cat 4 and will be racing mostly crits (have 2 stage races next year).

Thanks in advance.
