your making me think TOO much about tackle man...
QUIT IT!!!
I liked the Thunnus a lot..but for the money here in the US there are far better baitrunner "STYLE" reels out there...i dont think thier sales of the Thunnus did as well as they thought it would...why would you spend $200+ on a bait runner when you can buy an Okuma Epixor that is WAY better for under $100???
Anyway, over-seas..yea buddy they have the better ones over there for sure...my UK Shimano Big Baitrunner Long Cast is the exact frame as the Thunnus(6 ball bearings) but has the "big pit" style spool as the long didtance surf reels(holds 600 yrs of 12lb line!)
The "TOP of the LINE" in the US right now is made by Daiwa..its called the Grand Wave..its just an American Version of the top baitruner in the Uk called the Infinity(the UK verson will run ya about $500) heres the link..but WARNING, this is not a cheap priced reel, i know right now a carp angler that has TWO of them..but hes got $1000 of dollars in just carp tackle!

In my opinion, the Big baitrunner long cast is a better reel and costs a bunch cheaper(even with the $30 shipping i paid) than the grand wave from Daiwa.
I have had the original BTR's from shimano for YEARS and have landed so many fish on them(both the 3500 and 4500) but i just changed over to the Okuma Epixor and its a far better reel for sure!
10 ball bearings compared to the 4 ball bearings of the newer "B" series shimanos...it costs about $30-$40 less than the shimano..comes with TWO alum. spools, and they make WAY more sizes that just the basic 3 of shimano..PLUS they do make 3 KINDS of baitfeeders to choose from incase someone doesnt want to spend $80 on a new baitfeeder..from 2-3 ball bearings all the way to the 10 ball bearing reel!
Sizes..EB20, EB30, EB50 & EB60 (thats just the Epixor...the Cornado goes up to CD90 size now(its BIG)
I just got not long ago 2 EB50's for my new 13ft Carp rods and they are SWEET, i was going to put two BTR4500's on them, but after fishing with an Epixor EB baitfeeder..theres no comparison(again MY opinion).
Also if your in the market for a sweet light spinning rel for lures, check out the Metaloid(10bb) or the regular Epixor(10bb) for the price they cant be beat and im sad to say they are way smoother tham my high dollar Stradics
I got my yongest son Christopher(who just turned 7 Dec. 30th) his very first spinning combo, its a 5' UL rod with titanium eyelets and i put an Okuma Avenger AV15(95 yrds of 6lb test) on it for him..this UL reel has 6 ball bearings and is awsome..im going to buy my son Tyler one for his Fenwick for next year....its WAY better than his UL Sedona 500FA hes been using!
