I had the original Harrison Avon 1lb 6oz blank built by MT with a spliced 2oz tip as a chub rod a little while ago. It’s a tremendous little 11footer and would be equally as fantastic for perch.
I’d imagine it’s very similar to the chimera Avon in many ways.
As Joe rightly said though very expensive especially when you get crazy ticking all the boxes for spendy custom options.
As far as through actioned multi tip Avon rods go you’ll be hard pushed to better a used shimano from the 90’s/00’s
They had loads of them in the ranges from techniums, stradics, purists, Antares etc all brilliant rods and will be perfect for big chub, perch, roach, bream, tench and even in the right situation they’ll tame carp and barbel.
I’ve got a stradic specialist that cost me near bugga all yet it’s one of the most beautiful players rods I’ve ever used especially when a double figure barbel crashes your chub party.
