i know it may sound crazy but had better at the very least have your test in order up front here. It is unlikely that u would have issue getting it BUT it would sure suck to have to alter or change cruise and blast 1 year plan b/c you run out of required juice. You should IMO have all gear set if financially possible (may sound crazy but....)That(running out of required compound)would certainly throw a wrench in your game plan. Anyway....at 23 that not my idea of a good idea...but it is 100% personal choice.....best of luck to you...
