Yeah it might take you 44# for awhile, not sure on your skill level but usually experience lends to less weight all around.
To the original question, 25# is plenty of ditchable weight, 10-15# would be plenty. The problem I foresee and would warn of, moving all that weight to one place (be it a tank weight or ankles, anything) is how it affects your trim (position and attitude in the water). Placing weight in various places is usually more beneficial, its good to maintain some ditchable weight and I applaud the line of thinking. Be wary moving so much weight to a cam-band (My assumption) may not be the "fix" you are looking for.
