The general split varies league to league, but that split will give you a very strong offense. One of my leagues is like that, or even closer to 175-85. However, my other league goes as much as 190-70 or 195-65. It just depends on the league and how the owners value players.
From experience I can tell you to hold onto your draft sheet from this year's auction so you can refer back to it next year. Make some notes and keep it for next season--an invaluable tool!
