Please help with line recommendation

I recently purchase a TFO Pro 8126-4 for my first two hand rod. I use large and weighted flies. I got a recommendation to use an Airflo Compact Skagit in the 400-500 gr. weights. I am leaning towards the heavier side. I would appreciate your thoughts on a proper line. Thanks in advance.
