its going to boil down to your personal preference. another thing to consider to is the ability to use first strike rounds. tibs can do this stock while the tipx has to do some conversions. do you plan on using a remote line or stick with primary 12ies? is weight a concern to you? most important, how are you going to carry your gear while playing? the feel of the pistol in your hand and having a few games with them will tell you what you need to know. good luck though.
