That’s a shame, I’ve had nothing but excellent service from them in past.
If it was me i would then look at a shimano 5000 series baitrunner (xtea are the best, older aero GTs also good) you’ll pick the Aeros up on eBay for good money but the XTEAs tend to go for big money, but for a reason.
Also have a look at daiwa GS Br reels…not used one myself but being daiwa are bound to be decent and fairly cheap…so maybe use them for a few months until Thunnus back in stock and get yourself an early Xmas pressie
