Registering for the WildCard is the bonus with G.Loomis due to the fact that if you do step on the rod, crush it etc if gives you the choice to make a judgement call to either send it in cause a fish broke it and you think warranty should cover it. Or perhaps you snapped the handle in half in your tailgate and you know they will question it. Pull the card and you get a "freebie"
From G.Loomis website
"Wild Card: A service program offering a onetime, no questions asked, free, over the counter replacement. Only applicable to current rod models of NRX,Pro4xGLX and GL2."
Then of course on your 2nd rod your Limited Lifetime Warranty applies and for most all G.Loomis rods you pay a $20 processing warranty fee that includes the replacement of your rod and the return shipping that is as long as the rod is deemed warranty covered.
I haven't fished the GL2's but hear there great. Let me tell you however the Aetos lineup of rods is nice and after a year of selling lot's at the shop I've seen 1 or 2 out of many come back broken most likely due to angler error. Pure Fishing is never as fast as Shimano or Loomis most times when dealing with warranty but are 95% going to do a free replacement on any rod. You just pay shipping.
Good luck with your choice, the Elite Tech rods are well made and a little cheaper than both rods mentioned and are something to look at also.
