Your plan this far looks rockstar! I am but a newbie really, but your filtration ideas seems plenty. I have a 2217 and a 2213 on my 75 and it seems to be enough. With the attention to detail you seem to have down pat, and the high quality components you are setting up, I think your money in the bank. The DW is epic! I love it and cant wait to see it in action! Good luck and keep us all posted with pics........we love em!
