I havnt got to try the thera band yet but i think you would be fin with the gold as you have to cut your bands you can just cut it narrower and a bit longer to weaken it Ive been useing exercise band from walmart bout 10 bux for 3 bands 1 strong 1 med 1 week they all work well you just have to use more of the weaker ones to = the stronger one also when trying to fing a length that works find 1 that last longest then make it stronger by adding width or bands making it shorter will make it shoot faster but at a cost short band life with my extended fork ss with med bands on it 1 can put a 1/2 nut through ply wood easy cant wait to get some strong onthere or even some gold
hope this helps
