Requesting info for Concept Z (the orange one)

[Matthooper]

Learned pretty much all the pros and cons of this reel so I’m not looking for any opinions on performance. I’ve noticed that some sellers listing the specs have different sizes (100 or 200). Could anyone tell me what the difference is and applications are? I tried searches but nothing comes up. I know the larger number is usually a larger example of a reel. I did message 2 eBay sellers. One who had no size listed and they replied they were unsure what it was (even sent me all the specs. The other had one listed in the 200 size and they replied that they were made only in the 200/300 sizes. I have seen several sold in the 100 so what gives? Any insight would be great. Thanks y’all.
