I been doing a little research and I was wondering if I should continue using my 14 oz. Fairtex and Twins gloves on the heavy bag and pads? I know these gloves are technically training/sparring gloves, but I bought them with the intent of using them solely on the bag and pads and at 14 oz. for conditioning purposes. The reason I did not buy actual Bag Gloves is because they are very light, and I feel I would be missing out on that conditioning the 14 oz. gloves give me (I am around 120 lbs.) Do you guys think I should invest in some sturdy quality Bag Gloves and leave my other gloves to sparring? I have only used the Twins / Fairtex gloves a few rounds of sparring and padwork each, so I doubt they are damaged in any way.
