I don't think you need any rocker...Rocker is built into most 30'+ boats because they are so Big, Long,& Heavy thats the only way to get the nose up. Your boat isn't that long and adding rocker may cause you a porposing that you cant get rid of with trim or tabs. and if you can crack 100mph you don't need any, actually your at the point you don't want the nose up in the air anymore.
Now for removing the aft strakes, depending on how the hull is built, allot of the glass work may happen inside the boat (or it may not) but the glassman should let you know BEFORE he does it!!!! they are probably helping now more than hurting.
I think your at the point of trying different props and spacers to get all you can from what you got... If your bored out there take up online poker, leave your Kickazz boat (hull) alone....
WTF, Over.....WTF, 10-4.....
