If it had to be a loomis?

Ok, here is the situation. I have the opportunity to pick up a loomis spey rod at a substantial savings..So much so that it would be my cheapest option into a two hander. So my first question is, what loomis rod would you recomend for a beginner? I currently am a fairly proficient caster with a one hander. I will most likely be using it for summer/fall steel and silvers.

I have been eyeing these 2 models:
Glx 6/7 12'9"
Glx 0r Kispiox 7/8 13'4"

Which of these do you think would be better? Is the kispiox inferior to the glx? Can they handle tips well?

Sorry for all the questions but like I said its a great deal and I need to jump on board to make it happen.

Oh yeah, as far as a reel is concerned, I was looking at Teton Tiogas. What size would I need to hold the line? 10LA? What lines would accompany this rod well?

Thanks,
Drew
