Intelliflo and pool vacumn reccomendations.

I recently upgraded our pool equipment installing a raypak 407, Pentair 4060 DE and intelliflo pump. THe old hayward vac gets hung up in some spots using the lo flo pump. Does anybody have any opinions about different vacs ?
I was looking at the baracuda mx-8. Which vacs work better with lo flo pumps ? It is pushing approx 32 gal/min.
The energy savings is great. Any ideas would be appreciated.

Thanks,

What did you end up going with? I am in the same situation and had the first navigator and then the new hayward vac xl but it is having the same problem unless I'm over 40gpm. I'm wondering if the MX-8 would work any better.
