I've used a 1/4oz round head (on 10lb mono) with the 3.75 Thump Grub as a swimbait in clear water with great results... considering these were never designed to be used in this fashion, it has a great side to side swimming action and has tricked many a bass for me. My point is two-fold: first, either head should suffice, especially with a drop of super glue for extra holding power; and second, I don't think the heavy hook will be all that important at 25 feet because I'm not losing any in 6-8 feet using the standard Aberdeen the mold was designed for (although I am using lighter rods and longer casts because of the clear water).
