Which 3S Lipo should I get??

Well I had a looooooong meeting at work today and was sitting next to another teacher and fellow RC enthusiast. We thought about different ways to get a 3s in my XXX-T and sketched out an idea for a new retainer strap. I stopped by Home Depot on my way home and picked up a small piece of .093 Lexan. After some measuring, marking, cutting, heating, and bending this is the finished product. I think that it will work perfetly and I can still use the stock strap and my NIMH packs!! It only took about 20 minutes to make so if it does not fit perfectly once my batteries get here I can make another one. Now to order the 6000mah 3s2p 11.1v lipo pack from MaxAmps and see what this thing can do!!!
