As trout rigs go,matching the reel sz to rod sz is more for balance and aesthetic appeal imho,I wouldn’t get too hung up on backing capacity that you’re never gonna need,it’s only the rare huge trout on a large river that will even get you into your backing let alone come anywhere close to spooling you.....50m backing capacity is more then enough for 99.99% of resident trout you’ll ever hook into.
If a reel feels nice/well balanced/comfy etc....and of course looks good....I wouldn’t be too concerned with the number(s) that a reel mfr prints on it
Anadromous Salmon & Steelhead is another story........but even then,the importance of backing capacity is generally overrated,I’ve never come anywheres even close to being spooled by any searun fish having caught hundreds of Salmon/Steelhead on both coasts and in between on tributaries to 4 of the 5 Great Lakes.
