1/ : Take a look at what is written at the top of your handles, perhaps you have one "Made in Austria" and the other one "Designed in Austria", instead of 2 racquets manufactured at the same place ; it should explain some of the difference ("Designed in Austria" actually means that the racquet has been made in China, intead of Austria).
2/ Check the weights of your racquets, because if your head heaviest racquet is not also the lightest racquet, correcting the balance point by adding lead tape will not help very much the racquets to feel the same, because you would have then similar balance points but very different overall weights.
For exemple :
a/ if your Head heaviest racquet is also the lightest, then you just have to add weight inside the handle of that head heaviest racquet and you can almost match the Balance AND weight of your 2 racquets
b/ if your head heaviest racquet has the same weight as your other racquet, then adding lead tape can only match the balance points but the overall weight will be very different so your racquets will feel different.
c/ if your head heaviest racquet is is also the heaviest racquet, you have 2 solutions to match the balance poinst, one solution is adding weight in the handle of your heavier racquet, making the difference in weight even bigger between your 2 racquets, while you match the balance of your racquet, so the feel will be also different ; the other solution is to add weight upper the balance point of your lightest racquet, then you will approach the weight AND balance of the other racquet, but there is a strong risk that they won't feel the same anyway because if you try to add enough weight upper the balance point of your lightest racquet to match their balance points, chances are that you will have to add so much weight that it will have a too strong effect on the swingweight of the racquet that you modify so your racquets would still feel different.
Of course all what I said is conditionned by how much weight difference you have, between your 2 racquets
3/ Check if there is lead tape applied somewhere on your racquet (hidden under the CAP Bumper/grommets, or hidden between the handle and the grip), you may also put out the butt cap to see if there is some silicone injected in the handl of one of the racquets.
Personnaly I had many PT 630' with CAP, and the heaviest weighted 359 grams strung, and the lightest weighted 331 grams strung (with the same strings of course), weird QC from Head IMHO for those 2 racquets, but I have to admit that usually the strung weight of every others of my PT 630's were between 347 and 350 grams, so it is not so bad from head.
