I've never ran the QIV-X's to compare, so can't say for sure.
Based on the increased slip and less bow lift, I think you'd do well to try some 1" spacers. Another thing to try is to have your props labbed with more rake and cupping.
It's a Saber 28 Cyclone. Running Imco SC WITH -2" lowers. It is possible I may have to put a space and set the drive deeper. I am honestly not exactly sure how deep I am I am going to say about 2 below the stern. Runs 95 at 5600 with the 32s. It does cavitate a bit coming on plane but is awesome as soon as it comes over and it jumps on plane. Went from 10% Slip with standard length to 17.7 slip now. I'm making more RPM now and picked up 2-3 MPH especially when heavy.

I have the same issues with my labbed B1 30P. Causes more chine walk and needs a lot more trim. I have an older Hydro QIV that picks the bow way up over the B1 but it doesn't bite as well getting on plane. The B1 is way better for cruising but the Hydro is way better for top end. I can break both props loose easily even after I hit 30mph. I don't know how the air tubes work, if my Hydro prop breaks loose at all below 35, I have to stop to get it to bite again. I am hoping to try a Cutting Edge 5 blade this summer, I'm looking for the same thing.

Thanks for the info, my 32's break loose when getting on plane but I can back off and they are fine once it comes over. If I carried the bow more I think that will more top end without all the weight. And hopefully without spacers, it's cheaper that way. Lol Just means it won't work nothing usually fixes a boat problem inexpensive.

our set ups are similar as you know. only real difference is i'm 1.36 ratio . i'm running about the same 95mph with a set of hill propellers.
ido not feel any bow digging and if i get crazy with trim ( 8 or 9 on the indicators) my bow gets real light.
have you checked the bottom of the boat?

I don't remember is you have shorties, I do have -2".
If I trim much over 6 I start to lose speed, I did have your situation with standard length, in fact it loved to go airborn. Sounds fun but not really! Doesn't do that at all now. Regardless of trim I don't even throw a rooster at all. I have not checked the bottom.
