You have your strat decked not floating right? Youve changed brands of strings too? While I love to mod guitars to add fancy stuff I think it wont fix your problems of breakage at the tuner or unraveling of the butt end. You should look at these. Unraveling = 1. Too high tension on the trem springs (Most Likely). 2. Bridge saddle burr, swap the low E and the High E saddles. 3. Look at the angle of break of the string thru the trem plate up to the saddle it is actually breaking there If so there is a sharp edge on the trem plate. 4. Changing tunings without regard to the fact that during this some strings are being drawn past their limit, if you take off the tension of the lower strings then the top 3 have to take the load of the trem springs. Tuner breaks = 1. Breakage at the tuner is usually caused by slippage during installation, after the string has been bent through the hole but before you get the new string tensioned it slips a little then later that kink breaks. 2. The tuner has a sharp edge on the string hole from wear. 3. The string overlaps itself on the tuner shaft instead of laying flat this will cause it to cut the string. Sounds like you might want to go up to 11's, they are harder to break.
