Rope recommendations

Currently I have a 60m Edelrid Starling Pro Dry 8.2mm rope (it's a half/twin rope and not the Starling protect pro dry), which I use for general glacier crossing and double up as a half rope when climbing on alpine terrain. However, I am thinking about getting an additional 60m single/half/twin rope, so I can do ~60m pitches instead of 30m pitches and also have longer rappels. My main use would be for alpine climbing (PD to D terrain (5c or 5.9 max) both ice and rock, glacier crossing). I occasionally climb in a party of two or three people. Currently I am thinking about getting either:

  1. Get another Edelrid Starling Pro Dry 8.2mm rope, so I have two of the same ropes, which has its benefits. I feel like Edelrid was lying with the weight specs however, since the rope is rated at 47grams/meter which should result in 2820 grams, but when I weighted it, it was closer to 3200 grams, which is closer to 53grams/meter.

1a. Get a different type/ brand half rope.

  1. Get a triple rated 60m dry rope like the Petzl Volta Guide 9.0mm, or the Beal Opera 8.5mm unicore - golden dry and pair this with the Edelrid rope I already have.

2a. On top of the triple rated rope, get an additional Petzl rad/pur line and use this instead of the Edelrid rope, but this will be extremely expensive for 60m and wouldn't work as great for three people I think.

  1. Get two different lighter double ropes (sub 8mm), maybe like 40m in length. This would be a lighter setup, but I can't use it as a single and is a little short on the glacier for crevasse rescue with three or more people, unless I combine them.

I'm not sure at all what would be the most cost efficient and what would give me the most versatile and light setup, but my gut tells me that option 2 would be the best. You can't have all three of Cost, versatility(specs), and weight but please let me know your thoughts on what would be the best setup for my use case.
